# Chat Stream

`POST /api/chat/stream`

## Request

- Base URL: `https://fojin.app` (the document declares no server; this is the origin it was published from)
- URL: `https://fojin.app/api/chat/stream`
- Auth: none declared

Stream AI answer via Server-Sent Events (SSE). Same as POST /chat but with real-time token streaming.

Holds **no** request-scoped DB session. The endpoint takes neither
``Depends(get_db)`` nor ``Depends(get_optional_user)`` — the latter
carries its own ``get_db`` yield-dependency, which FastAPI keeps checked
out until the StreamingResponse body is fully sent, i.e. the entire
60-120s LLM window, pinning a PG connection per active stream
(project_fojin_db_pool_streaming). Instead the raw bearer token is read
off the request and the user is resolved INSIDE the generator's
short-lived prep session. The generator owns two short-lived sessions
(prep + save) and holds none across the LLM I/O.
