Background Check API Integration

1 Our multi-jurisdictional criminal database searches form the core of our offering

With well over 1,000+ sources and 650 million criminal records, our database offers you the best coverage in the the industry*. Other firms might give you information that is a mile deep but only an inch wide when you order a background check. However, at our cost effective database search options offer your organization the best way to instantly expand your coverage with a better chance of finding more criminal record information on your subject.

The accuracy of database searches is heavily reliant on the refresh rate of the data sources that we acquire. When we receive an update file from one of our sources, we make sure that the new records are searchable within days not weeks or months. Our partners and resellers can be confident that, unlike other methods of searching criminal data, the information returned is not stagnant and out of date.

Even with the most extensive record set available, any search is only as strong as the query search logic tied to the data.'s search logic employs algorithms that are a key advantage which is proven in side-by-side comparisons against competing database searches.
