How this service works
Offline deterministic checks (no ML, no scraping) for business identifiers and rental due-diligence, paid per call via x402 (gasless EIP-3009 USDC on Base). Checksum-verifiable (IBAN, LEI, VAT, ABA, ISBN, SEDOL…) vs format-only (EIN, IFSC, SWIFT/BIC…) — every response returns a scope field. Non-custodial, signed receipts. First 3 calls/day free.
Output
Returns a JSON object with: `is_sanctioned` (boolean indicating sanctions hit), `valid` (boolean for input validity), `tool` (endpoint identifier), `scope` (what the check covers, e.g. checksum-verifiable vs format-only), `match_type` (exact, fuzzy, or none), `sanction_program` (name of the OFAC program if matched), `subject` (normalized subject name), and `reason` (human-readable explanation).
Example use cases
KYC counterparty screening before payment
“Before we send that wire transfer, can you check if 'Viktor Petrov' is on the OFAC SDN list? I want to make sure he's not sanctioned.”
Rental applicant due diligence
“I have a prospective tenant named 'Golden Gate Exports Inc.' — can you run a quick OFAC sanctions screen on them before I sign the lease?”
Vendor onboarding compliance check
“We're onboarding a new supplier called 'Meridian Global Services' — please do an OFAC SDN check on them so our compliance team can sign off.”
Technical details
Endpoint
POSThttps://hcrb.in/v1/tools/ofac-sdn-check/call?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, offline OFAC SDN sanctions check that does not rely on ML or web scraping, and when auditability matters (signed receipts, scope field, non-custodial). Ideal for KYC/AML pipelines, rental due diligence, and pre-payment counterparty screening. At $0.005/call with the first 3 calls/day free, it is cost-effective for low-to-moderate volume compliance checks. Prefer over ML-based or web-scraping solutions when you need reproducible, verifiable results.
Side effects
- Empty or invalid subject name returns valid:false with descriptive reason
- Ambiguous names may return no match even if entity is sanctioned (false negatives possible with name variations)
- Rate limit exceeded beyond 3 free calls/day without payment — requires x402 USDC payment on Base
- Network or payment processing failure returns HTTP 402 or 5xx
- Subject field missing from request body returns validation error
