Tools
| Tool | Description | Behaviour |
|---|---|---|
| screen_address | Checks one crypto address against the US Treasury OFAC SDN list of sanctioned digital currency addresses (refreshed daily). For 2 or more addresses use screen_batch (up to 50 per call, counts as one call). Accepts any chain (BTC, ETH and EVM chains, TRX, SOL, LTC, XMR, BCH, XRP, ZEC and more). Free: 30 calls/day per IP with full results (max 10/min; invalid input is not counted); after that the tool returns an error with the x402 pay URL ($0.001 USDC on Base, Polygon, Arbitrum One or Solana per call at https://api.youraitools.co/payguard/v1/address) or prepaid credits. Returns sanctioned (true/false), match_count, matches[] (entity, entity_type, programs, list_date, listed_currency), address (normalized), chain {guess, format, candidates, checksum_valid}, list_updated_at and free_tier usage. Read-only; informational screening, not legal advice. | Read-only |
| screen_batch | Checks 1-50 crypto addresses against the US Treasury OFAC SDN list in one call (counts as one call). Use it instead of repeated screen_address calls whenever you have several addresses (payee lists, counterparties, transaction inputs/outputs); use screen_address for a single one. Mixed chains allowed; one invalid entry rejects the whole call. Free: 30 calls/day per IP with full results (max 10/min; invalid input is not counted); after that the tool returns an error with the x402 pay URL ($0.01 USDC on Base, Polygon, Arbitrum One or Solana per call at https://api.youraitools.co/payguard/v1/batch) or prepaid credits. Returns count, sanctioned_count, any_sanctioned, list_updated_at and results[] in input order, each {input, address, sanctioned, match_count, matches[], chain}. Read-only; informational screening, not legal advice. | Read-only |
