How this service works
Pre-payment counterparty risk check for AI agents: OFAC sanctions (names, aliases, wallets), domain age and email authentication, vendor and executive impersonation domains, routing/IBAN/SWIFT/wallet validation, and invoice-fraud signals. Returns proceed/review/block, explained findings and a signed receipt.
Output
A JSON object containing a risk decision (proceed, review, or block), a list of explained findings covering OFAC sanctions matches, domain age and email authentication signals, impersonation domain detections, payment instrument validation results (routing/IBAN/SWIFT/wallet), and invoice fraud indicators, plus a cryptographically signed receipt for audit purposes.
Example use cases
Screening new vendor before payment
“I need to pay a new supplier called Global Parts Inc. for the first time — their invoice comes from finance@global-parts-inc.net and their website is global-parts-inc.net. Can you run a risk check on them before I approve the wire transfer?”
Crypto wallet sanctions check
“Before I send 5 ETH to wallet address 0x4e83...f2a1 for a freelancer named Alex Petrov based in Russia, can you screen that wallet and counterparty for OFAC sanctions or any fraud signals?”
Invoice fraud detection for AP team
“Our accounts payable agent just received an invoice from CFO@contosogroup.co — which looks different from our usual vendor domain contoso.com — for $47,000. Can you check whether this email domain is an impersonation attempt and whether we should block this payment?”
Technical details
Endpoint
POSThttps://counterpartycheck.com/v1/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent is about to authorize or recommend a financial payment and needs a pre-payment compliance gate — especially for new or unverified vendors, large wire transfers, crypto payments, or any scenario where invoice fraud or sanctions exposure is a concern. Prefer this over manual compliance checks or generic fraud APIs when you need a single call that combines OFAC screening, domain fraud signals, impersonation detection, and payment instrument validation with a signed, auditable receipt.
Side effects
- Missing required counterparty name returns 400 validation error
- Unrecognized country code may reduce screening accuracy
- Newly registered domains with no history may return insufficient data for a definitive decision
- OFAC database latency may cause occasional delays or stale results
- Wallet address format errors return validation failure
- Payment of $0.25 USDC via x402 must succeed before check is performed; failed payment returns 402
