Errors

Predictable error bodies

Machine-readable error codes with stable JSON shapes. Full guide with fixes on the error reference.

401api_key_requiredNo Authorization: Bearer header on a protected endpoint.

401invalid_api_keyThe presented key does not exist or is malformed.

401expired_api_keyThe key passed its expires_at timestamp.

401revoked_api_keyThe key was revoked by its owner or an administrator.

403blocked_api_keyThe key was administratively blocked (abuse or policy).

Evidence & safety boundary

Educational decision-support only

The API does not diagnose, does not prescribe medical treatment, does not replace professional judgement, and does not claim measured laboratory validity unless measured data are supplied. Read the full boundary.
