Errors have the shape `{"statusCode", "name", "message"}`. See [Errors](https://docs.pidgely.com/errors/) for the full list.

| Status | Name | When |
|---|---|---|
| 401 | `missing_api_key`, `restricted_api_key` | No `Authorization: Bearer` header, or a `sending_access` key called an endpoint that needs `full_access`. |
| 403 | `invalid_api_key`, `validation_error` | The API key is invalid or revoked, or the request is not allowed for this account (unverified domain, plan limit, paused account). |
| 404 | `not_found` | The resource does not exist in this account (or the id is not a valid UUID). |
| 422 | `validation_error` | A field is missing or invalid; `message` names it. |
| 429 | `rate_limit_exceeded` | Too many requests per second. Wait for `Retry-After` seconds. |
