OFAC SDN Name Fuzzy-Match Screening (Probabilistic Indicator)

Machine Tool Interface · fuzzy-match-sanctions

$0.015 / callPaid per call · 0 free tier No signup

Name-similarity comparison against an identified OFAC CSV snapshot or historical local fallback. Reports source, content hash and evidence status. Deterministic Unicode-preserving token-set + Jaro-Winkler scoring, without transliteration/alias expansion. Program labels belong to the stored record and may be historical. Current legal status is unknown; NOT a sanctions clearance, identity resolution or UN/EU screen.

Honest Scope Guarantee

Deterministic, offline, explainable — no ML, no scraping. The response's scope field states the exact assurance level.

Quickstart & Execution

cURL (Paid-only route — unauthenticated calls return HTTP 402 Payment Required)

curl -X POST https://index.code402.dev/v1/tools/fuzzy-match-sanctions/call \
  -H "content-type: application/json" \
  -d '{"name":"Lazarus Group","threshold":0.85}'

This route is paid-only (0 free calls/day); every unauthenticated request returns an HTTP 402 Payment Required challenge with its payment terms. Machines use USDC on Base; card credits (instant Stripe checkout) are enabled in this deployment. Signed XDR-1 receipts authenticate recorded service claims, not independent settlement, delivery or zero-knowledge proofs.
