OFAC sanctions check API for crypto wallets and names

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

EU sanctions screening API: code samples in curl, Python and Node, and monthly plans.

Check a crypto wallet against the OFAC SDN list before you pay it (EVM, BTC, TRX), or screen a person or company name, with aliases, against OFAC, the EU consolidated list, the UN Security Council list and the UK Sanctions List in one call. Returns a verdict (block, review, pass), each match with list, list ID, programme and strength, and every list's date. Screening aid, not legal advice. Use before paying; with wallet risk: check_counterparty.

When to use it

Inputs

Name	Type	Description
`address`	string	Crypto address to check against OFAC (give address, name or both)
`name`	string	Person or company name; matches when every word appears in a listed name or alias
`lists`	string	Lists for a name: all (default), or any of ofac, eu, un, uk, comma-separated. Addresses are checked against OFAC, the only list that publishes crypto addresses

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://glyphcall.com/sanctions/check?address=0x098B716B8Aaf21512996dC57EB0615e2383E2f96"

Or one of your 3 free calls, no key:

curl "https://glyphcall.com/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 or Solana over x402; Base or Tempo over MPP) and retries.

Questions

Which list does it check?

The US Treasury OFAC SDN list, including aliases and the listed digital currency addresses. Each match comes with its SDN ID, programs and the list date.

Is this legal advice?

No. It is a screening aid; confirm any match against official OFAC records before acting.

How do I pay?

Each successful call costs $0.009; failed calls are not charged. The first 3 calls are free (25 through an MCP client). Then pay with card credits (from $1; the key goes in an Authorization header or, for clients that can only fetch a URL, as api_key= in the URL) or per call in USDC over x402 or MPP. No account is needed.
