## Other responses

- `400`: The inputs core refuses (`issues`), or a body that is not `{"inputs": …}`.
- `404`: Not there, or not shown: a dataset the site may not show answers exactly as one that does not exist.
- `413`: A body over 256 KB.
- `415`: Compute takes `application/json` only.
- `429`: Over the keyless limit for this sender. Come back after `Retry-After` seconds.
- `500`: A tool or its data failed. The answer never says what.
