# Screening API

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]`
