What is public

Authenticate with Authorization: Bearer fm_live_…. The contract is OpenAPI 3.1 at /openapi.json on the API host.

  • GET and POST /api/v1/inboxes
  • GET and PATCH /api/v1/messages and GET /api/v1/messages/:id
  • GET /api/v1/search
  • POST /api/v1/emails for transactional send

The same scopes and mailbox limits as Agent Keys apply. A send that needs approval returns 202 with status: approval_required and does not send.
