## Other responses

- `400`: The request did not match the schema
- `401`: No valid credentials. WWW-Authenticate names the protected resource metadata to start from
- `402`: The balance cannot cover Describe
- `403`: The credentials are valid but not enough: the token lacks the scope, or the action needs a browser session rather than an app token
- `404`: Not found
- `409`: The idempotent request is still being completed
- `422`: The media is unreadable or blocked
- `429`: Rate limited. RateLimit names the policy; Retry-After says when to try again
- `500`: Internal server error
- `503`: Describe is unavailable or pending recovery
