Uniqueness Engine — API Authentication

Every paid enrichment endpoint requires a revocable API key sent as a Bearer token. Signup is email-verified and never returns a key inline.

Bearer token

Send your API key on every authenticated request:

Authorization: Bearer <api_key>

Programmatic signup

  1. POST /api/signup with {email, client_name, device_name} → 202 transaction
  2. Poll GET /api/signup/verification/:transaction_id with X-Verification-Token
  3. After status: approved, claim once via POST .../claim

Key rotation

Compromised key: POST /api/account/rotate-key. Lost key: sign in at /account and rotate all account keys.
