The widest native AML coverage in a unified crypto API

Many providers offer address screening only through third-party add-ons or partner integrations. CryptoAPIs offers first-party AML — sanctions, fraud and KYT — as part of the same API you already use for blockchain data and wallet tracking.

20+

Chains screened

Sanctions, fraud and illicit-activity screening across 20+ blockchains — not a handful of major chains.

Address & transaction

Screen both a wallet address and a full transaction (KYT) — including the flagged participant addresses, risk score and risk band.

Unified API

Compliance lives in the same REST API as data, wallet tracking and market data — no separate compliance vendor to integrate.

Frequently Asked Questions

What does the Verify Address / AML API do?

It provides two AML screening capabilities. Transaction screening (KYT) checks crypto transactions in real time so exchanges, PSPs, wallets and custodians can monitor activity as it happens, and address screening checks any wallet address against sanctions and fraud signals. Both return categorized compliance flags you can act on within your own workflows.

Does the AML API screen against OFAC, EU and UN sanctions lists?

Yes. Address screening checks crypto addresses against OFAC SDN, EU and UN consolidated sanctions lists. It also flags exposure to fraud-related categories such as phishing, ransomware, darknet markets and mixers.

Which blockchains does the address screening support?

The product advertises coverage across 20+ blockchains through a single REST endpoint, including Bitcoin, Ethereum, Polygon, BNB Smart Chain, Tron, Solana, Arbitrum, Optimism and Avalanche. One integration is meant to handle addresses across the supported chains.

Can I monitor transactions for compliance (KYT), not just addresses?

Yes. The Screen Transaction endpoint provides Know Your Transaction (KYT) checks for real-time monitoring, aimed at exchanges and custodians. This complements address screening so you can evaluate both counterparties and the transactions themselves.

Are screening calls logged for audit and compliance?

Yes. The product states that every screening call is logged and retrievable, which supports audit trails for regulatory reporting.
