https://app.agent-task.com/api/v1. The OpenAPI document is at https://app.agent-task.com/api/v1/openapi.json and Swagger UI is at https://app.agent-task.com/api/v1/documentation.

Send an API key as a Bearer token (Authorization: Bearer amk_…). Keys carry scopes such as tasks:read or tasks:write, and the API enforces the required scope per endpoint. The MCP endpoint also supports OAuth 2.1 browser sign-in.

Combined API + MCP volume is 2,500 requests/day on Free, 10,000/day on Pro, 50,000/day on Team and 1M/day on Enterprise.
