 Are the Autocomplete, Name to Domain, and Risk APIs Free?

Clearbit's Autocomplete and Name to Domain API are completely free product that you can use without a subscription. You also do not need to use an API key when sending requests to the API. 

Do I Need a Clearbit Account to Use these APIs?

The Autocomplete and Name to Domain APIs do not require a Clearbit account; however, the Risk API does require one.

Are they Regularly Maintained?

Because these products are free, it is available as-is and is not regularly maintained by our engineering team. The data returned by the API is completely curated by automations, meaning while the data is still very accurate there are sometimes outlier inaccurate results returned by the API that can persist for some time until the automation finds them and corrects them.

How Many Requests Can I Make with Each API?

You can make 600 requests per minute to each API (unless you are using Streaming or Reveal). Check the returned HTTP headers of any API request to see your current rate limit status.

Why am I Seeing Errors while Using the Name to Domain API?

Since a company name is not a unique identifier, you should be prepared for some inherent inaccuracy in the name-to-domain results.
