}CompliAPI helps you stay compliant and steer clear of bad actors, wherever they are. One token, one GET request, one definitive answer.
Get startedThe list of rules keeps growing. We track every change so you don't have to. Pick the compliance APIs your business needs and skip the rest.
GET /api/v1/screen/crypto/{address}
Screen Bitcoin, Ethereum, Stellar and other blockchain addresses against the official OFAC Specially Designated Nationals (SDN) and Blocked Persons List. We handle every list update, so you can focus on building.
Explore the wallet screening APIGET /api/v1/screen/email/{email}
Verify whether an email address is tied to a sanctioned entity before it touches your platform, and get the OFAC source record for every match.
Explore the OFAC APIGET /api/v1/screen/website?address={website}
Check websites and domains against the SDN list to avoid interacting with bad actors, wherever they are.
Explore the OFAC APIGET /api/v1/screen/id/{id}
Look up passports, driver's licenses, tax IDs and other government-issued IDs. A partial ID returns candidate matches ranked by similarity, so you have the context to decide whether to escalate.
Explore the OFAC APIGET /api/v1/screen/country/{country}
OFAC doesn't publish one list of countries. Instead it runs comprehensive, targeted and military programs. CompliAPI curates those designations into a single, simple lookup.
Explore the OFAC APIGET /api/v1/geo
Many finance and crypto apps must treat users in the United States, or in New York State, differently. A simple geo lookup lets your app do that and stay compliant.
Explore the geofencing APIGET /api/v1/vpn
Geo-blocking only works when the IP reflects the user's real location. A companion VPN signal tells you when it doesn't, so your country controls hold up.

Every screening endpoint is also an MCP tool, so AI agents and assistants can run the same checks directly — same API token, same audit trail.

We rebuilt CompliAPI from the ground up — a faster screening API, live entity stats, and a first-class MCP server so AI agents can run OFAC checks too.

ENS domains can hide addresses, so both the domain and its linked Ethereum address must be checked against the OFAC list for compliance.
