The Ipregistry API uses API keys to authenticate requests. You need to pass it as a key query parameter:

If you do not include your key when making an API request or use one that is incorrect or outdated, Ipregistry returns an error.

Managing API keys

You can view and manage your API keys in the Ipregistry Dashboard.

Ipregistry allows creating multiple API keys per account to separate concerns but also restricting usage per IP addresses, origins or throttle/rate limit invocations per hour.
