# Chat Stream

`POST /chat/stream`

## Request

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

One turn as a sequence of events, so the colour arrives first.

The blocking /chat runs tool, then a second model round for
commentary, then returns everything together -- so the customer waits
the full turn to see a palette that existed a third of the way in.

This yields the visual the moment the tool returns and streams the
commentary after it. Same tools, same metering, same entitlement
check, same result object; only the delivery changed. /chat is
untouched for anything that wants one JSON body.

## Request body

- ChatRequest
  - `session_id` string, required
  - `message` string, required
  - `history` unknown[]
    - unknown
  - `image_ref` string

## Response `200`

Successful Response

## Other responses
