OFAC sanctions check: wallet or name

$0.009 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

OFAC sanctions check: screen a crypto wallet address (EVM, Bitcoin, Tron and more) or a person or company name against the OFAC SDN list and get a verdict (block, review, pass) with every match, SDN id and program. A screening aid, not legal advice. Use before paying or accepting funds, or when onboarding a counterparty.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://tools.funwords.eu/ofac/check?address=0x098B716B8Aaf21512996dC57EB0615e2383E2f96"

Or one of your 25 free calls, no key:

curl "https://tools.funwords.eu/ofac/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 or Solana over x402; Base or Tempo over MPP) and retries.
