## Other responses

- `400`: Validation failed — `error` names each offending field (`field: message`).
- `401`: Missing, malformed or unknown credentials (`WWW-Authenticate: Bearer …` is set).
- `403`: The credential lacks the `contacts:read` scope (body `{ error: "insufficient_scope", required, missing }`), or the team is suspended.
