Add live STI verification to your platform

Quick start

Apply for an API key below. Pass it in the X-API-Key header with every request.

GET https://testedclear.com/api/v1/verify?token=USER_TOKEN
X-API-Key: tc_live_your_key_here

const res = await fetch(
  'https://testedclear.com/api/v1/verify?token=USER_TOKEN',
  { headers: { 'X-API-Key': 'tc_live_your_key_here' } }
)
const { verified, panel, tested_date, retest_by } = await res.json()

if (verified) {
  showVerifiedBadge({ panel, tested_date, retest_by })
} else {
  showRetestPrompt()
}

Verify endpoint

Response schema

// 200 OK — verified and within testing window
{
  "verified": true,
  "panel": "Full STI Panel",
  "tested_date": "2026-04-01",
  "retest_by": "2026-07-01",
  "issuer_type": "clinic",
  "status": "current"
}

// 200 OK — retest window has passed
{
  "verified": false,
  "reason": "retest_due",
  "retest_by": "2026-04-01"
}

// 200 OK — user revoked their credential
{
  "verified": false,
  "reason": "revoked"
}

// 404 Not Found — token does not match any credential
{
  "verified": false,
  "reason": "invalid_token"
}

All non-error responses return verified as a boolean — that is the only field you need to gate access on. Treat any non-200 status (other than 404) as a transient failure and retry.

Errors & status codes

Errors are returned as JSON with an error field and the status code in the HTTP response.

Every error response includes docs and apply URLs so that unfamiliar consumers of the API get pointed to the right place.

Auto-expiration

Rate limits & pricing

Usage is metered per-month per-key. Each successful call counts as one unit. Calls that return 4xx errors do not count against usage.

Developer tier is capped — once you hit 100 calls in a month, the endpoint returns 429 until the 1st of next month. Paid tiers allow overage and bill automatically through Stripe.

Badge embed (free)

The simplest integration — an iframe that renders a small verified badge. Uses format=badge on the standard verify endpoint and counts toward your monthly call quota.

<iframe
  src="https://testedclear.com/api/v1/verify?token=USER_TOKEN&format=badge"
  width="220" height="60" frameborder="0"
  style="border:none;border-radius:10px;"
></iframe>

Badge Display API

For integrations that want richer badge options (SVG, HTML with display name, JSON for native rendering), use the dedicated Badge Display endpoint. Requires a tc_badge_ key — a separate key class from the verify-API tc_live_ key.

// JSON — render your own badge UI
const res = await fetch(
  'https://testedclear.com/api/v1/badge?token=USER_TOKEN',
  { headers: { 'X-API-Key': 'tc_badge_your_key_here' } }
)
const { verified, display_name, panel, tested_date, retest_by, badge_url } = await res.json()

// SVG — drop-in image tag
// <img src="https://testedclear.com/api/v1/badge?token=USER_TOKEN&format=svg" />

The JSON response includes display_name when the user has set one — useful for rendering a personalized badge alongside a user's profile.

OAuth for linked apps

For apps that want verification status tied to a specific TestedClear user account (rather than a shareable link), use the OAuth 2.0 authorization code flow. The user consents in their TestedClear account, your app receives a long-lived access token, and you can then check verification status without the user ever sharing a link with you.

OAuth is a separate integration pathway — contact api@testedclear.com to onboard as a partner and receive a client_id and client_secret.

1. Redirect the user to authorize

GET https://testedclear.com/api/oauth/authorize
  ?client_id=YOUR_CLIENT_ID
  &redirect_uri=https://yourapp.com/callback
  &response_type=code
  &state=RANDOM_CSRF_TOKEN

The redirect_uri must exactly match one of the URIs registered with your partnership. After the user consents, they're redirected back with ?code=...&state=... appended.

2. Exchange the code for an access token

POST https://testedclear.com/api/oauth/token
Content-Type: application/json

{
  "grant_type": "authorization_code",
  "code": "AUTH_CODE_FROM_CALLBACK",
  "client_id": "YOUR_CLIENT_ID",
  "client_secret": "YOUR_CLIENT_SECRET",
  "redirect_uri": "https://yourapp.com/callback"
}

Auth codes expire after 10 minutes and are one-shot — they can only be exchanged once. Store the resulting access_token securely on your server.

3. Check verification status

GET https://testedclear.com/api/oauth/me
Authorization: Bearer ACCESS_TOKEN

// Verified
{
  "verified": true,
  "panel": "Full STI Panel",
  "tested_date": "2026-04-01",
  "retest_by": "2026-07-01",
  "issuer_type": "clinic"
}

// Retest due
{
  "verified": false,
  "reason": "retest_due",
  "retest_by": "2026-04-01"
}

// No active credential
{
  "verified": false,
  "reason": "no_active_credential"
}

The OAuth endpoint returns the same verification shape as the verify API but tied to the user who consented — no token-sharing required. Same auto-expiration semantics apply.
