### I18n

Grape supports I18n for parameter-related error messages, but will fallback to English if
translations for the default locale have not been provided. See [en.yml](https://github.com/intridea/grape/blob/master/lib/grape/locale/en.yml) for message keys.

Make this link relative, without the whole https://... thing, it will just work.



## Headers

Request headers are available through the `headers` helper or from `env` in their original form.

You should write this in a more concise way:

::I18n.translate(key, options) || ::I18n.translate(key, options.merge({ ... }))

When the locale is missing, an empty string is returned which does not evaluate to false, so the test doesn't pass with this change.
