Authentication is handled with a simple API key.
You can attach your API key to a request in one of two ways:
- Via the `Authorization` HTTP header.
- Via the apiKey query string parameter.
We strongly recommend the latter one so that your API key isn't visible to others through logs or request sniffing.
If the API key is not appended correctly, or if the API key is invalid, you will receive the following HTTP error “401 - Unauthorized”.
