API reference
unauthorized — HTTP 401
Missing or invalid API key.
Example response
{ "ok": false, "request_id": "req_...", "error": { "code": "unauthorized", "message": "Missing or invalid API key." } }
Why it happens
- The Authorization header is missing or not in the form `Bearer tf_live_...`.
- The API key was revoked in the dashboard, or has a typo.
- The key was pasted with surrounding whitespace or quotes.
How to fix it
- Send the key as `Authorization: Bearer tf_live_...` on every request.
- Check the key's status at transcriptfetch.com/app/keys — revoked keys never work again; create a fresh one if needed.
- Verify the key with a free call to GET /api/v1/me — it returns your credit balance when the key is valid.
Retryable? No — retrying with the same key will keep failing. Fix the credential first. Every error response carries a
request_id — include it when contacting support.
