Every method has its call ready in cURL, TypeScript and Python. Send its typed input and get JSON back in its output schema.
Read the API docs
Claude Code, Codex and Cursor can then search, build and run your methods over MCP, without driving a browser themselves.
Get a key for your agent

Wait up to 60 seconds for the answer, or read a longer run later by its id.
