The screening api provides a simple restful interface for checking whether an address is blocked or not against a multiple data sources. Right now, two data sources are supported:

Blacklist URL: a json list of addresses that are blocked
Chainalysis: the Entity API runs a screen against an address to quantify the risk associated with it, Severe, High, Medium, or Low.

Addresses themselves are checked against specific rulesets:

https://screener-url/[address]
