How To Use Domain Score API

Determine domain name reputation programmatically with an API request.

Domain Score API use case

In case you are dealing with a lot of signups on your website, and you want to give special treatment to VIP users our Domain Score API can detect high-profile domains.

Domain Score API

Scoring is not a real-time process as we are doing multiple checks before returning the result to you. For this reason, there are 2 steps:


1. Send domain for scoring (Set task API);
2. Check the scoring state (Get result API).


These two APIs are described in detail below.

Keep in mind that making a request to “Get result API” and skipping the first step will result in an empty reply.

We provide a webhook solution if you would like to get notified when the result is ready.

More details are below.

Webhook Support

If you like to receive the processing result to your URL as soon as it’s ready add “webhook_url” parameter to the API request like this:




Our system will make POST request to the specified URL passing JSON in the request body, like this:




The body will contain Array of all domains as Objects. Object fields match API reply fields.

Webhook system supports requests resending in case your URL is not accessible (any HTTP error). In this case we will make 5 retries with the following delays: 5, 15, 30, 60, 60 minutes.
