Talk to an agent live from a browser over one WebSocket, and read back the logs those preview calls leave. A phone call's transcript and recording are in Conversation Logs.

5 endpoints

Your access token works like a password: it never expires and reaches your whole account. Keep it out of source control and client-side code.

Worth knowing before you start

Two paths need their trailing slash. /logs/list_file/ and /logs/read_log/ answer 307 without it, and the redirect may point at an absolute host — which breaks calls made from a browser.
Not every response is JSON. Recording and export endpoints return audio, CSV or PDF. Read Content-Disposition for the file name rather than parsing the body.
Prefer the upsert when writing an agent. Create or update an agent creates the agent when it does not exist yet and updates it when it does, in one call.
