OFAC sanctions screening for a wallet or name

$0.005 per call · failed calls are never charged · no account or API key needed

Screen a crypto wallet address or a person or company name against the US Treasury OFAC SDN list, including aliases and the listed digital currency addresses (BTC, ETH, USDT, TRX and more). Returns each match with SDN ID, programs and match strength, plus the list date. A screening aid, not legal advice. Use before paying, onboarding or trading with a counterparty.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/sanctions/check?address=0x098B716B8Aaf21512996dC57EB0615e2383E2f96"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/sanctions/check?address=0x098B716B8Aaf21512996dC57EB0615e2383E2f96&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum, Monad, World Chain or Tempo) and retries.
