## Other responses

- `400`: `BAD_USER_INPUT`: an invalid parameter, body, path, setting, access level or role. `field` names the argument when known, and `details` carries structured detail (the misses of `PATCH /v2/pens/{id}/files`).
- `401`: `UNAUTHENTICATED`: a missing or invalid key, a deleted owner, or a Team key for a Team that is not PRO.
- `403`: `FORBIDDEN`: a write to a Pen made in the classic editor, or a plan limit (non-Public access, a Private Collection, file size, storage, collaborators). The message names the limit and, when a bigger plan would lift it, where to upgrade.
- `429`: `RATE_LIMITED`: the owner exceeded the plan's requests in an hour, its reads today, or today's allowance of Pen or Collection creates. No `Retry-After` or rate-limit headers are sent; the body carries `retry_after_seconds`, `limit` and `reset_at`.
- `500`: `INTERNAL`: unexpected, and reported; the message is generic.
