 `handle` never throws: every failure is a response. `path` is the path below where the API is mounted (`/todos/4`), `query` a `URLSearchParams`, `body` the parsed JSON.

+`nodeListener` from the core serves `node:http` with nothing else installed. It mounts the API under `prefix` and answers `404 not_found` outside it, reads JSON bodies up to 1 MiB (`maxBodyBytes`), and builds each request's context with `context`:

+```ts
+http.createServer((req, res) => (req.url?.startsWith('/api/') ? api(req, res) : site(req, res))).listen(3000);

+Without HTTP at all, call `rest.handle` directly: [From your own code](#from-your-own-code).
