Yes, you can!
The authentication is made with a key which you will have to add to every call you make to our API. This parameter is always required. We will return an error if the key is missing or invalid.
Your API key is what identifies your account, so make sure to keep it secret! You can at any time generate or delete API keys on your dashboard.
A special API key can be used to test our API:
test-api-key. It will validate the provided parameters, but will always return the same, dummy, response. It is available on our three main endpoints: the Domain Search, the Email Finder, and the Email Verifier.
