It has a `GET` operation that could return an error.

It has a `POST` operation that could return several errors.

Both *path operations* require an `X-Token` header.

Sie verfügt über eine `GET`-Operation, die einen Fehler zurückgeben könnte.

Sie verfügt über eine `POST`-Operation, die mehrere Fehler zurückgeben könnte.

В нём описана операция `GET`, которая может вернуть ошибку.

Ещё есть операция `POST` и она тоже может вернуть ошибку.

Обе *операции пути* требуют наличия в запросе заголовка `X-Token`.
