# Router Answer

`POST /router/answer`

## Request

- Base URL: `https://mcp.physea.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://mcp.physea.ai/router/answer`
- Auth: none declared

Run the ROUTER on a question and return a typed answer + classification +
run_id. If callback_url is set, POST the result back to it (outbound).
(Relocated from POST /answer — C2 gives /answer to the renamed /solve
synthesis semantics; this classify→frame→typed-output pipeline keeps its
own address.)

  - `question` string, required
  - `context` string, nullable
  - `resources` string, nullable
  - `callback_url` string, nullable
  - `caller` string
