How to Choose the Right Sanctions Screening API for Your AI Agent

A comparison of OFAC screening APIs and what to look for: agent-native design, crypto wallet support, free tier, and integration options.

Not all sanctions screening APIs are built for autonomous agents. Here is what to look for.

1. Does it support crypto wallet addresses?

Many enterprise screening tools only check names and countries, which leaves the biggest risk for an agent unscreened. Your agent almost certainly pays crypto wallets, so wallet-address coverage is non-negotiable. agentmail screens 947 OFAC-sanctioned crypto addresses across EVM chains, Bitcoin, Solana, and Tron before any payment is signed.

2. Can agents call it programmatically?

An API is only useful to an agent if the agent can actually invoke it mid-workflow. Look for MCP support (the AI-native tool protocol), a simple HTTP endpoint, and a CLI for scripts. agentmail supports all three, whereas a PDF report or dashboard-only product cannot be called by an autonomous agent at payment time.

3. Is there a free tier?

You should never have to pay just to test whether a compliance control works. agentmail gives 5 free checks per day with no signup and no API key, so you can wire screening into your agent and verify it end to end before spending anything. A required sales call means it is not built for agents.

4. Does it log for audit?

OFAC expects documented, timestamped screening, and an audit trail is what turns a violation into a mitigated one. Choose an API that records every check with its result and the SDN-list version. agentmail paid plans include a full audit dashboard with timestamped, exportable logs that serve as your compliance evidence.

5. What is the latency?

Agent payment flows are real-time, so a slow screening call degrades the entire user experience or times out the transaction. Sub-second response is the bar to clear. agentmail screens in under 100 milliseconds, fast enough to sit inline before every payment without the agent or its user noticing the check.

The verdict

For AI agents, agentmail is purpose-built. Enterprise tools like Chainalysis, World-Check, and ComplyAdvantage are designed for human analysts, not autonomous payment pipelines.
