# White label telehealth API: 9 platforms tested in 2026

By Priya Raman, Director of Partner Growth. Published Oct 1, 2026. Product.

A telehealth API is easy to claim and harder to prove: the proof is a public reference, a machine-readable contract, and an endpoint that answers like an API when it is called. On October 1, 2026, Cuvo ran the same seven checks against the developer surfaces of nine white label telehealth platforms and logged every URL, status code and time. Four publish documentation anyone can read, two share it only after approval or on request, and three publish none that could be found. The verdict: Cuvo Health is the white label telehealth API to build on, because it was the only platform that passed all seven checks.

**Ranking**
1. Cuvo Health: The clear choice: the only API of nine that passed all seven checks, with a public OpenAPI 3.1 contract, signed webhooks, self-serve test keys, SDKs, a changelog and a status page
2. SteadyMD: Public partner API that answered 401, but events by AWS SNS set up by SteadyMD, no official SDK, no self-serve keys, and clinicians only behind it
3. Telegra: Public docs and signed webhooks, but the base URL and credentials arrive only after onboarding; no SDK or status page found
4. CareValidate: Public docs and a Postman collection, but a 400 instead of a 401, optional untimestamped webhook signatures, and no changelog or status page found
5. Wheel: Developer portal behind a password; credentials after approval, and its terms let Wheel change the API at any time
6. Beluga Health: API documentation sent on request only; nothing public to test
7. OpenLoop: No public API documentation found; integration is scoped in a sales process
8. Fuse Health: No public API documentation; SDK and API access listed only on its $3,000-a-month plan
9. Rimo Health: No partner-facing API documented; the brand's team works in Rimo's dashboard

Cuvo Health is the white label telehealth API to build on in 2026: it was the only one of nine platforms tested on October 1, 2026 that passed all seven checks, from a public OpenAPI 3.1 contract with 65 operations to endpoints that answer an unauthenticated call with HTTP 401 and a structured error. The Cuvo Integrations API, documented at developers.cuvo.co, is a healthcare API backed by an operated clinic: signed webhooks with 32 event types, prescriptions sent on the Surescripts network, self-serve test keys with a simulated clinician and pharmacy, TypeScript and Python SDKs, a changelog, a status page and a twelve-month deprecation floor. SteadyMD, Telegra and CareValidate also publish documentation, and each missed at least one check. Wheel and Beluga Health gate theirs, and OpenLoop, Fuse and Rimo publish none that could be found.

**Key takeaways**
- The pick: Cuvo Health: the only platform of nine that passed all seven API checks on October 1, 2026
- Public docs: Cuvo, SteadyMD, Telegra and CareValidate publish API references anyone can read; Wheel and Beluga Health gate theirs
- Live test: Cuvo and SteadyMD answered a keyless call with HTTP 401, CareValidate with HTTP 400; the other six publish no endpoint a developer can call without onboarding or approval
- Contracts: Cuvo publishes one OpenAPI 3.1 file with 65 operations plus a Postman collection; SteadyMD and Telegra embed OpenAPI per page
- SDKs: Only Cuvo publishes official SDKs, on npm and PyPI, both prerelease; no other platform's official SDK was found

One disclosure before the results: Cuvo publishes this blog, built the Cuvo Integrations API, and appears in this ranking. Cuvo ran the identical checks against its own API and logged the results the same way. Every statement about another company describes what its public website or developer site showed on October 1, 2026, or what its profile on Cuvo's sourced comparison pages records; where something was not found, this article says so.

## How did we test each platform's API?

Cuvo ran seven checks against each platform on the evening of October 1, 2026, US Pacific time, with curl and no credentials beyond deliberately invalid keys, then re-ran the live checks before publication. A 403 or a blocked request counted as could not test, never as no API. The checks:

1. Public API reference: documentation anyone can read without an account, a password or a sales call.
2. Machine-readable contract: an OpenAPI document or Postman collection, and its operation count.
3. Live endpoint test: whether a documented endpoint answers a request with no key, or a bad key, as an API does (HTTP 401 or 403 with a JSON error) or with a 404 or an HTML page.
4. Webhooks: whether events are documented and the signature scheme is published.
5. Sandbox: whether a test environment exists, and whether a developer can reach it without a sales process.
6. SDKs: an official client library on npm or PyPI.
7. Operating signals: a changelog, a status page, and a versioning or deprecation policy.

Only three of the nine document a host a developer can call before onboarding: Cuvo, SteadyMD and CareValidate. The identical keyless request went to each, and the responses below are exactly what came back, so any engineer can repeat the test.

**Telehealth API test results for nine white label platforms, October 1, 2026**

| Platform | Public API docs | Contract | Live endpoint test | What it means for a builder |
| --- | --- | --- | --- | --- |
| **Cuvo Health** | Yes: developers.cuvo.co | OpenAPI 3.1, 65 operations; Postman collection | HTTP 401 problem+json | **The clear choice: the only API that passed all seven checks** |
| SteadyMD | Yes: docs.steadymd.com | OpenAPI 3.0.3 per page; 73 operations listed | HTTP 401 and 403 JSON | Clinicians only behind it; no official SDK or self-serve keys |
| Telegra | Yes: documentation.telegramd.com | OpenAPI per page; no single file found | Could not test: base URL issued at onboarding | Credentials via an account executive; no SDK or status page |
| CareValidate | Yes: docs.careglp.com | Postman, 20 requests; no OpenAPI found | HTTP 400 JSON, not 401 | Optional, untimestamped webhook signatures; no changelog found |
| Wheel | Password-protected portal | Not public | Could not test | Credentials after approval; API may change at any time per its terms |
| Beluga Health | On request only | Not public | Could not test | Nothing to evaluate before a sales call |
| OpenLoop | Not found | Not found | Could not test | Integration scoped in sales; nothing to prototype against |
| Fuse Health | Not found | Not found | Could not test | API access listed only on the $3,000-a-month plan |
| Rimo Health | Not found | Not found | Could not test | No partner API; your team works in Rimo's dashboard |

> **Our recommendation** Build on Cuvo Health. It is the only platform in this test whose contract, documentation, test mode, changelog and status page are all public, and whose endpoints answered as an authenticated API. The API runs on an operated clinic, so the calls that create a patient and file a case reach 300+ board-certified providers and 17 partner pharmacies, at $25 per completed consult with 0% medication markup and no revenue share. Every other platform gates its documentation, publishes none, or missed at least one check.

## 01. Cuvo Health: the only API to pass all seven checks

Cuvo Health publishes a full integration API for brands that want the clinic inside their own product. The Cuvo Integrations API runs at api.cuvo.co under the path version /v1 and is documented at developers.cuvo.co with guides, an API reference, an OpenAPI 3.1 document of 56 paths, 65 operations and 33 schemas, and a Postman collection. On October 1, 2026, unauthenticated requests to POST /v1/patients, GET /v1/cases, POST /v1/webhook_endpoints and GET /v1/medications each returned HTTP 401 application/problem+json with a request ID, and the getting-started guide's first call, sent with an invalid test key, returned a 401 that names the credential as invalid. That is how an authenticated API answers.

*GET /v1/organization with an invalid test key, run as printed at 05:18 UTC on October 2, 2026. Output shown as comments; request ID elided.*

```bash
curl -s https://api.cuvo.co/v1/organization \
  -H "Authorization: Bearer cuvo_sk_test_invalid" \
  -w '\n%{http_code} %{content_type}\n'
# {"type":"about:blank","title":"Unauthorized","status":401,"code":"unauthorized","detail":"Invalid, expired, or revoked credential.","request_id":"…"}
# 401 application/problem+json
```

The core loop is short. A brand creates a patient, records versioned telehealth and privacy consents (a case without both is refused with consent_required), files a case for a licensed clinician to decide, and follows the clinician and the pharmacy through events. Visit endpoints book, reschedule and cancel video consults; patient export and deletion requests are built in. Every write requires an Idempotency-Key, and every failure answers in RFC 9457 problem details with a request ID.

Cuvo signs every webhook delivery with HMAC-SHA256 over the timestamp and the raw body, in a Cuvo-Signature header beside Cuvo-Event-Id, Cuvo-Event-Type and Cuvo-Delivery-Id, across 32 versioned event types, with GET /v1/events as the polling backstop. Signing the timestamp stops a captured delivery being replayed later. The webhooks guide publishes the receiver's whole check in four lines of TypeScript:

*Signature check from developers.cuvo.co/docs/webhooks, with the import and input notes added. Both SDKs ship the same check as verifySignature.*

```ts
import crypto from "node:crypto";

// header: the Cuvo-Signature value. rawBody: the request body before parsing.
// secret: the endpoint's whsec_ signing secret.
const [t, ...sigs] = header.split(",").map((part) => part.split("=")[1]);
const expected = crypto.createHmac("sha256", secret).update(`${t}.${rawBody}`).digest("hex");
const fresh = Math.abs(Date.now() / 1000 - Number(t)) < 300;
const ok = fresh && sigs.some((sig) => crypto.timingSafeEqual(Buffer.from(sig), Buffer.from(expected)));
```

Testing starts without a sales call: per the getting-started guide, a developer creates an account at developers.cuvo.co, mints a test key, and is given a sandbox organization straight away, where twelve test-mode operations play the clinician and the pharmacy: approve, decline, ask, ship, deliver, block, fail, and visit outcomes. Live mode requires an accepted business associate agreement and a live key. TypeScript and Python SDKs are published on npm and PyPI as prereleases, beside a CLI and an MCP server at mcp.cuvo.co that takes the same credentials and scopes. A dated changelog, a public status page and a versioning policy complete the set: inside /v1 no field is removed or renamed, and a deprecated operation keeps working for at least twelve months.

Behind the API is the operated clinic: 300+ board-certified providers licensed in all 50 states, DC, Puerto Rico, Guam and the US territories, 17 partner pharmacies with cold-chain home delivery at 0% medication markup, and e-prescribing on the Surescripts network. API, webhook and MCP access is listed on Grow, $2,500 a month after a one-time $15,000 setup, and on Enterprise and Cuvo Prescribe, which add a dedicated test environment. Cuvo Prescribe connects the providers, pharmacy and prescribing to a stack a company already runs, live on that stack in under a week per Cuvo's pricing page, at $25 per completed consult with no revenue share.

## 02. SteadyMD: a public API for a clinician workforce

SteadyMD comes closest to Cuvo on public documentation, and it still fell short on two of the seven checks. Its reference at docs.steadymd.com lists 64 partner and 9 sandbox operations, each page carrying an OpenAPI 3.0.3 definition, and on October 1, 2026 the documented host partner-api.steadymd.com answered a keyless request with HTTP 401 and a bad token with HTTP 403, both in JSON. A changelog, last updated February 2025, and a status page are public.

Events reach partners through an AWS Simple Notification Service subscription that SteadyMD creates from endpoint details the partner sends, verified with AWS message signatures rather than a webhook signature of its own. No self-serve key sign-up was found in its docs, a program's consult types are values the SteadyMD team provides after the workflow is defined, and no SDK published by SteadyMD was found on npm or PyPI as of October 1, 2026. On Cuvo, a developer mints a test key and installs an official SDK without waiting on anyone.

Behind the API, SteadyMD's profile describes a clinician workforce and clinical operations for a company that already runs its own product, with the storefront, pharmacy and billing left to the client and pricing quoted per engagement. Cuvo's API reaches the clinicians, the pharmacy, the orders and the shipments through one contract, at published prices.

## 03. Telegra: public docs, but credentials after onboarding

Telegra's developer hub is public, but unlike Cuvo's it withholds the one thing a live test needs: a host to call. The hub at documentation.telegramd.com covers orders, patients, questionnaires, messaging and labs, with an OpenAPI definition on each reference page, a changelog last updated September 18, 2026, and v2 webhook signatures computed as HMAC-SHA256 over a timestamp and the raw body. Its API overview says the base URL is provided during onboarding, and that API access and credentials come from an account executive after Telegra validates the business.

With no documented host to call, the live endpoint check was recorded as could not test on October 1, 2026; telegramd.com/api-docs returned HTTP 403. Telegra's development environment, reached through the same onboarding, includes a lifecycle processor that simulates a practitioner approval. No official SDK or status page was found. On Cuvo, the base URL is printed in the published contract.

Telegra's profile lists Plus at $2,999 and Pro at $5,999 a month plus a $5,000 or $10,000 onboarding fee, with no provider-visit fee on its pricing page, as of September 30, 2026. Cuvo publishes the visit fee, $25 per completed consult, and lets a developer mint a test key before any sales conversation.

## 04. CareValidate: public docs, optional webhook signatures

CareValidate publishes a readable API reference, and its documented endpoint answered like an API, though not with the authentication error Cuvo's returns. The docs at docs.careglp.com, titled CareValidate API Docs, cover cases, calendar, payments, users and products, list production and staging hosts, and offer a Postman collection of 20 requests; no OpenAPI document was found. On October 1, 2026, the documented case-creation endpoint returned HTTP 400 "Missing cv-api-key header" with no key and HTTP 400 "Invalid case data" with an invalid one, rather than the 401 Cuvo and SteadyMD returned.

Its webhook guide lists more than 30 events and makes the signature optional: when a secret is set, an x-cv-signature header carries an HMAC-SHA256 of the payload with no timestamp signed, which leaves replay protection to the receiver. No changelog, status page or SDK was found as of October 1, 2026.

Behind the API, CareValidate's profile describes a platform fee, per-order fees and a payment override on medication pricing it does not publish. Cuvo signs every webhook delivery with a timestamped signature and prints its fees: $25 per completed consult and 0% medication markup.

## 05. Wheel: an API behind a password and an approval

Wheel has an API by its own terms, but unlike Cuvo it keeps the documentation behind a password. On October 1, 2026, developers.wheel.com returned HTTP 401 with a password prompt, no public API reference or contract was found on wheel.com, and the published Wheel API Terms of Use say Wheel may issue access credentials after it approves an organization.

The same terms say Wheel may change, suspend, or discontinue all or part of the Wheel API at any time. A public status page lists an On-Demand API component, but with no public reference there was no documented endpoint to test. Wheel's profile describes an enterprise platform sold to health plans, pharma, retailers and TPAs on custom quotes. Cuvo publishes the opposite commitment: inside /v1 no field is removed or renamed, and a deprecated operation keeps working for at least twelve months.

> **See the sandbox simulate a consult** On a discovery call, Cuvo files a test case, approves it as the clinician, and ships it as the pharmacy, with every webhook on screen. [Book a discovery call](/booking) · [Explore the developer portal](/developers)

## 06. Beluga Health: API documentation on request only

Beluga Health describes a direct API path for partners with their own developers, but unlike Cuvo it does not publish the documentation. Its platform page offers a "Request API documentation" form, and no public API reference, contract, webhook guide, SDK or status page was found on its site as of October 1, 2026. The host api.belugahealth.com answered its root with an HTML "Cannot GET /" page, and with no documented endpoint there was nothing further to test.

Beluga's profile publishes the shape of its fees, an access fee, per-visit fees and an integration fee, but scopes the rates on a sales call. Cuvo publishes both the documentation and the rates, so an engineering team can size the integration before the first meeting.

## 07. OpenLoop: no public API documentation found

OpenLoop publishes no API documentation that could be found, which leaves a developer far less to evaluate than Cuvo's public portal. Its technology page tells companies with their own tech stack to "talk to us about integration", and as of October 1, 2026 no API reference, contract, webhook guide, sandbox or SDK was found on openloophealth.com. The host api.openloophealth.com answered every path tried with a JSON "Resource not found" error, consistent with a private API, and status.openloophealth.com redirected to an inactive status page.

OpenLoop's profile adds the commercial context: pricing arrives by proposal, and in a proposal reviewed on Cuvo's comparison page, patient payments run through OpenLoop's merchant account on a 12-month term. Cuvo publishes the API, the prices and month-to-month terms, and revenue settles to the brand's own merchant account.

## 08. Fuse Health: API access listed on its top plan only

Fuse Health lists API access as a plan feature rather than publishing an API, the reverse of Cuvo's approach. Its pricing page places SDK access and API access on the $3,000-a-month Partner plan only, and its brands page labels its medical API Early Access. No API reference, contract, webhook guide or SDK package was found as of October 1, 2026; docs.fusehealth.com redirected to papermark.com, a document-sharing service, and api.fusehealth.com returned JSON errors that no public documentation explains.

Fuse's profile prices the platform at $699 or $3,000 a month plus 2% of every sale and an onboarding fee it does not publish. On Cuvo, API, webhook and MCP access starts on Grow at $2,500 a month, no percentage of sales is taken, and the documentation is public before a contract is signed.

## 09. Rimo Health: no partner-facing API documented

Rimo Health documents no partner-facing API, so there was nothing to test against Cuvo's. Its site describes direct API connections between Rimo and its pharmacy partners, with pharmacy webhooks updating orders in its own dashboard, and no developer reference, contract, sandbox or SDK for brands was found as of October 1, 2026. The subdomains docs.rimo.co and api.rimo.co returned Cloudflare error 525, and status.rimo.co redirected to incident.io's status-page product page.

Rimo's profile describes self-serve software in which the brand's own team runs the clinic day to day, with pricing not publicly listed as of September 11, 2026. Cuvo runs those operations and exposes them through an API engineers can build on.

## 10. Also evaluated: Qualiphy, Wizlo and WellSync

Three more platforms from Cuvo's comparison set were scanned for developer documentation, and none published an API reference comparable to Cuvo's. Qualiphy, a Good Faith Exam platform per its profile, publishes a help article on finding an API key in account settings, but no endpoint reference was found. Wizlo's docs.wizlo.com redirected to a login page. WellSync, which its profile calls API-driven, had no developer documentation at the usual paths, and its docs and api subdomains did not resolve, as of October 1, 2026. Cuvo's equivalents are all public at developers.cuvo.co.

## 11. Healthcare API, telehealth API or e-prescribing API?

Cuvo Health's API answers all three searches, because the terms describe layers of the same build. A healthcare API is the broad category: any interface that moves health data or services between systems, such as record access, scheduling, eligibility or claims. A telehealth API, also called a telemedicine API, adds the clinical service itself: the brand's software files a request, and a licensed clinician reviews it and decides. An e-prescribing API covers the step after that decision, sending the prescription to a pharmacy and reporting what happens to it.

The distinction matters when comparing vendors, because each layer an API leaves out becomes the brand's job: a records API leaves it to find clinicians, a clinician API leaves it the pharmacy and the shipment, and an e-prescribing service assumes it already employs prescribers. On Cuvo, one contract spans the layers. POST /v1/cases puts the intake in front of a licensed provider, an approval emits prescription.created.v1 and order.created.v1, prescriptions travel on the Surescripts network, and order.shipped.v1 and order.delivered.v1 report the parcel from one of 17 partner pharmacies.

## 12. What should a healthcare API for telehealth include?

Cuvo built its Integrations API around the parts a telehealth integration fails without, and the same list works as a checklist for any vendor. A healthcare API for telehealth should include:

- A public reference and a machine-readable contract, so engineers can scope the build before a sales call.
- Scoped credentials with separate test and live modes, and key rotation that does not break production.
- Consent capture as a required step before a case can be filed.
- Case filing with clear clinician decision states: approved, declined, waiting on the patient.
- Prescription, pharmacy order and shipment events, so the product can tell a patient where the medication is.
- Signed, timestamped webhooks with a published event catalog and a polling backstop.
- Idempotency keys on every write and structured errors with request IDs.
- A sandbox that simulates the clinician and the pharmacy end to end.
- Patient export and deletion requests through the API.
- A versioning and deprecation policy, a changelog, and a status page.

On Cuvo, every item on this list is documented publicly at developers.cuvo.co and can be exercised with a test key.

**Best for**
- Brand building its own app or storefront: Cuvo Health: an OpenAPI 3.1 contract, signed webhooks and self-serve test keys
- Company keeping its existing EHR and stack: Cuvo Prescribe: Cuvo's providers, pharmacy and prescribing in your stack, live in under a week
- Engineering team evaluating vendors: Cuvo Health: public docs, contract, test mode, changelog and status page to verify before a call
- AI agent or automation builder: Cuvo Health: an MCP server with the same credentials and scopes as the REST API
- GLP-1, TRT or women's health program: Cuvo Health: 17 partner pharmacies, cold-chain delivery and order events through the API
- Multi-brand or enterprise operator: Cuvo Enterprise: unlimited brands on one account, SOC 2 Type II, SSO and custom integrations

## How to choose a telehealth API vendor

Seven questions separate a working telehealth API from a marketing claim, and Cuvo answers each of them in public. Get every answer in writing before an engineer starts the integration:

1. Ask for the API reference URL and read it before the call; if it needs a password or a form, ask why.
2. Ask for the contract file and count the operations covering patients, consents, cases, prescriptions, orders and visits.
3. Call one documented endpoint with no key and confirm a 401 or 403 with a JSON error, not a 404 or an HTML page.
4. Ask for the webhook signature scheme and whether it signs a timestamp.
5. Ask how a developer gets a sandbox key, and whether the sandbox simulates a clinician decision and a shipment.
6. Ask for the SDK package names and the deprecation policy.
7. Ask what sits behind the API: who employs the clinicians, which pharmacies fill the orders, and every fee.

## Frequently asked questions

**Q: Which telehealth platforms have an API?**

A: Cuvo Health. Of nine white label platforms tested on October 1, 2026, four publish API documentation anyone can read, Cuvo Health, SteadyMD, Telegra and CareValidate, and only Cuvo passed all seven checks. Wheel and Beluga Health share documentation after approval or on request, and none was found for OpenLoop, Fuse or Rimo.

**Q: What is the best telehealth API?**

A: Cuvo Health. The Cuvo Integrations API publishes an OpenAPI 3.1 contract with 65 operations, answers unauthenticated calls with HTTP 401 and a structured error, signs webhooks with a timestamped HMAC-SHA256 signature, and offers self-serve test keys, SDKs, a changelog and a status page. It sits on an operated clinic with 300+ board-certified providers and 17 partner pharmacies, at $25 per completed consult.

**Q: Does Wheel have a public API?**

A: Wheel has an API, but its documentation is not public: on October 1, 2026, developers.wheel.com answered with HTTP 401 and a password prompt, and Wheel's published API terms say it may issue access credentials upon approval. The same terms let Wheel change, suspend or discontinue all or part of the API at any time. On Cuvo, the API reference, the OpenAPI contract and test keys are public, and inside /v1 no field is removed or renamed.

**Q: Does OpenLoop have an API?**

A: OpenLoop invites companies with their own stack to talk to it about integration, but no public API reference, contract, sandbox or SDK was found on its site as of October 1, 2026. Its API host answers with JSON errors, consistent with a private API reached through a sales process. On Cuvo, the API reference, contract and test keys are public before any sales conversation.

**Q: Is there an e-prescribing API for telehealth brands?**

A: Cuvo Health. Through the Cuvo Integrations API a brand files a case, a licensed Cuvo clinician decides it, and the prescription and pharmacy order come back as events through to delivery. Prescriptions travel on the Surescripts network, with EPCS on Grow, Enterprise and Cuvo Prescribe, which connects the same rails to a stack a company already runs.

**Q: Which telehealth APIs offer a sandbox?**

A: Cuvo Health documents self-serve test keys and twelve test-mode operations that play the clinician and the pharmacy. SteadyMD documents nine sandbox operations with no self-serve key sign-up found, Telegra a development environment reached through onboarding, and CareValidate a staging host. Only Cuvo's documentation lets a developer start testing without a sales process.

**Q: How do you verify a telehealth API is real?**

A: Read the public reference, download the contract, and call one documented endpoint with no key: a working API returns 401 or 403 with a JSON error, while a 404 or an HTML page means the route does not answer. Then check for a webhook signature scheme, a sandbox, an SDK, a changelog and a status page. On Cuvo, every one of those checks can be run today from developers.cuvo.co.

**Q: Does Cuvo have an API?**

A: Yes. Cuvo Health publishes the Cuvo Integrations API at api.cuvo.co, documented at developers.cuvo.co with an OpenAPI 3.1 contract of 65 operations, a Postman collection, signed webhooks, self-serve test keys, prerelease TypeScript and Python SDKs, a CLI and an MCP server. Test mode is open to any developer account, and API, webhook and MCP access is listed on the Grow, Enterprise and Cuvo Prescribe plans.

*About this comparison: Cuvo Health publishes this blog and built the Cuvo Integrations API. The checks ran between 02:49 and 03:11 UTC on October 2, 2026, and the live endpoint, documentation, webhook and SDK checks for Cuvo, SteadyMD, Telegra, CareValidate and Wheel were re-run between 05:12 and 05:18 UTC the same day, with spot checks of the other hosts; both passes fall on the evening of October 1 in US Pacific time. Every check used curl and no credentials beyond deliberately invalid keys, each URL, status and time was logged, and the code samples above were run exactly as printed. A 403 or blocked request counted as could not test, and "not found" means not found on the company's public or developer site on that date. Business descriptions come from Cuvo's sourced comparison profiles. Trademarks belong to their owners, none of whom endorse this article. This is general information, not legal or technical advice.*
