## Notes

- **Language**: the API answers Icelandic only; the wording is kept as sent and status is read from it.
- **Time zone**: Iceland is UTC all year, which is what the `+00:00` times are.
- **Unknown numbers**: Pósturinn answers an unknown number with an empty HTTP 204, reported as `not_found`.
