Metaculus project questions

Returns Metaculus question rows for one public project, filtered by its slug. A slug that does not exist returns 404.

Response behavior

- `data.feed` is `project`. - Every returned question belongs to the requested project; `data.questions[].projects[].slug` carries it. - A project slug that does not exist returns `404`, not an unfiltered feed. - A project that exists but currently has no questions returns `200` with an empty `data.questions`. - Invalid slugs or limits return invalid-parameter errors before upstream IO. - Upstream authentication, challenge pages, or parser drift is returned as a typed upstream error.

API key required. Paste a full key or rotate one from the API Keys page.
