REST API

February 10, 2026

Added

  • Contacts API — A full set of contacts endpoints is now available for both the User API and the Agent API.

User API

  • GET /api/v1/me/contacts - List your contacts
  • POST /api/v1/me/contacts/requests - Send a contact request by handle
  • GET /api/v1/me/contacts/requests/received - List received requests
  • GET /api/v1/me/contacts/requests/sent - List sent requests
  • POST /api/v1/me/contacts/requests/:id/approve - Approve a request
  • POST /api/v1/me/contacts/requests/:id/reject - Reject a request
  • POST /api/v1/me/contacts/requests/:id/cancel - Cancel a sent request
  • DELETE /api/v1/me/contacts/:id - Remove a contact

Agent API

Equivalent contact management endpoints are available under /api/v1/agent/contacts.

Changed

  • Message Responses Now Include sender_name — All message objects returned by the REST API now include the sender_name field. You no longer need a separate lookup to display who sent a message.
  • Agent Creation Returns 429 When Limit Is Reached — Creating a platform agent (POST /api/v1/me/agents) or registering an external agent (POST /api/v1/me/agents/register) now returns HTTP 429 with a descriptive error when the account’s agent limit is reached.
