Agents Developer Help

Every agent you build is also an API.

Call your deployed agents from your own backend, app, or website — stream responses in native LangChain format, upload files for your agent to read, and inspect its model and capabilities.

Developer API

  • Runtime API — getting started

    Call your deployed Agentman agent from your own code: base URL, agent-token authentication, and a first streaming request in under a minute.

  • Call your agent — the streaming API

    POST /v3/agent/stream: the request body, every SSE event type, and working curl and JavaScript clients for streaming agent responses in native LangChain format.

  • Agent info, models, and capabilities

    GET /v3/agent/info, /v3/agent/models, and /v3/agent/capabilities — everything your client needs to initialize: agent configuration, available models, and what file types the agent can read.

  • The Files API — upload, attach, manage

    Upload files your agent can read, attach them to streaming calls, mint presigned URLs, and validate accessibility — the full /v3/files reference with examples.

  • Use your skills in Claude Managed Agents

    Give Anthropic's Managed Agents access to your Agentman skills library — the two-part MCP config, the credential vault that signs it in, and the one piece Studio doesn't issue yet.
