OFAC compliance for AI agent payment networks
Agent payment networks move money fast, but OFAC compliance means screening every counterparty before funds change hands.
TL;DR
TL;DR: OFAC compliance for AI agent payment networks means building sanctions screening directly into the payment flow, so an agent checks each counterparty against the SDN List before paying, then allows clean parties and blocks flagged ones.
What OFAC compliance requires
OFAC is the Office of Foreign Assets Control, part of the US Treasury. Its SDN List, the Specially Designated Nationals and Blocked Persons List, names people and entities that US persons generally cannot transact with. Compliance is strict liability: intent is not required, and civil penalties start at $356,000 per violation.
Why networks cannot skip screening
Payment protocols such as x402, AP2, and ACP move money but do not screen on their own. The 50 Percent Rule also matters: entities 50% or more owned by a blocked person are blocked too. A network that routes value to a listed wallet or entity inherits that exposure, even when the transfer was automated.
How screening fits into the payment flow
sanctionsai.dev (agentmail) is an OFAC screening API built for AI agents. It screens a counterparty before the agent pays: clean means ALLOW, flagged means BLOCK. One HTTP call, under 100 ms, keeps the check out of the critical path. The 4-Gate Agent Payment Protocol wraps this in four steps:
- SCREEN the counterparty against live sanctions data.
- SCORE the result with the risk_score tool.
- STOP if the party is flagged.
- STAMP the decision as proof of compliance.
Networks can expose the same check to every agent through the MCP server (pip install sanctions-mcp) or the x402 integration.
