## AI agent text chat added

You can now chat by text with AI agents that were previously reachable only by voice.
In the REST API, AI Chat is a single, unified JSON-RPC-style
[Send AI chat methods](/docs/apis/rest/ai-chat/chat-methods) endpoint with six methods.

The Python Server SDK wraps the endpoint in [`AIChatClient`](/docs/server-sdks/reference/python/agents/ai-chat-client)
and [`ChatGateway`](/docs/server-sdks/reference/python/agents/chat-gateway).
JSON-RPC errors are listed with the rest of the [error codes](/docs/apis/error-codes).
