Quick Answers

Direct answers to common questions about OFAC sanctions screening for AI agents.

What is OFAC sanctions screening?

OFAC sanctions screening checks whether a wallet address, name, or country appears on the US Treasury's Specially Designated Nationals (SDN) list before a transaction is completed. SanctionsAI performs this check in under 100ms.

How much does SanctionsAI cost?

Free tier: 5 checks per day, no API key required. Paid plans start at $19/month or $0.05/check via x402 micropayments.

What happens if my agent pays a sanctioned wallet?

OFAC penalties reach $377,700 per violation under strict liability. There is no automation exemption. The operator is responsible for all agent-initiated transactions.

How fast is the sanctions check?

Under 100ms for wallet, name, and country screening combined. Fast enough for real-time agent payment pipelines.

Which blockchains are supported?

SanctionsAI screens 947 OFAC-sanctioned crypto addresses across EVM (Ethereum, Polygon, Arbitrum, Base, Optimism), Bitcoin, Solana, and Tron networks.

Is the data up to date?

Yes. The SDN list is refreshed daily from the US Treasury. The crypto wallet registry updates when new addresses are added to the source repository.

Can I self-host?

Yes. SanctionsAI is MIT licensed and available on GitHub. Self-hosting is free and unlimited.

Do I need an API key?

No. The free tier (5 checks/day) requires no API key, no signup, and no credit card. Just call the API.

What is strict liability?

Strict liability means you are responsible for OFAC violations regardless of intent. Even if your agent accidentally pays a sanctioned entity, you are liable. There is no "I didn't know" defense.

Does SanctionsAI integrate with MCP?

Yes. SanctionsAI ships as an MCP server (pip install sanctions-mcp). Any agent framework that supports MCP can use it directly.
