How to try it here

Authentication using Base64 encoding

Note for developers

API requests require authentication using HTTP Basic Authentication with an API key. The API key serves as the username, while the password field should be left empty. The format to encode is: your\_api\_key: (note the trailing colon).

This string must be Base64-encoded and included in the request's Authorization header as follows: 

Authorization: Basic encoded\_value

You can generate the encoded value using a trusted Base64 encoder.
