FAQs

What are Class A and Class B calls?

The majority of our API calls are Class A, including IP Summary, IP WHOIS, Referral WHOIS and RDNS. Our reverse-search API calls are Class B. To see the exact list, check out our API Explorer.

Where can I see API documentation?

Comprehensive API documentation is available in OpenAPI 3 (Swagger) format in our dashboard. Enterprise feed users also receive detailed schema documentation and usage notes.

Is the API reliable?

Yes. The API is hosted using the Amazon Web Services cloud. It is a fully serverless autoscaling design, utilizing AWS API gateway as the front end and Cloudfront for global distribution. You can expect it to be up when you need it.

Will I need to buy additional API access later on?

Our model is that you pay one price, and you get complete access to our API for that price. We don't offer add-ons: what you see is what you get.

What is commercial use?

Use of our API or data obtained from it as part of any business, including display of the data in internal and external-facing applications. This usage is allowed on any of our paid plans. However, you may not re-sell API access.

What are derivative works?

If you combine our data with other data, you create a derivative work. This is allowed on any of our paid plans, provided the result is not shared outside your organization. However, if you make the derivative work available to external users, then you must contact us to discuss Enterprise licensing.

Do you offer data that isn't available via the API?

Full data fields are available to vetted Enterprise customers for the purposes of fraud prevention, maintaining or enhancing network or information security, and indicating possible criminal acts / threats to public security. We do not offer data for direct marketing or any similar purpose.

Do you offer a free plan?

We can offer free plans for charitable and many other non-profit organizations. Contact us for more details.
