> Documentation for building on OneSay: the Control API, Task voice over the Realtime WebSocket, realtime voice (RTC), the JavaScript and ESP32 SDKs, MCP and the Console.

The API and SDK reference pages are generated from the OneSay specifications; where a guide and a reference page differ, follow the reference. Never share Production credentials, device secrets, connection tickets, customer audio or transcripts. MCP does not carry realtime audio.
