Sanctions & PEP Screening

Screen a name against 5 real sanctions/PEP sources in one call, with fuzzy matching so close variant spellings still surface.

0.01 USDC per requestactive

Base mainnet · x402 v2 · USDC exact payment

What you provide: a JSON request matching the input contract below.

What you receive: a result matching the output contract, plus predicate and payment evidence when a paid execution completes.

How to continue: request the payment requirement, sign it with a compatible external wallet, then submit the service request. Payment occurs outside ChatGPT.

Acceptance predicate

Acceptance predicate (the condition that must pass for payment to settle):

{
  "type": "all",
  "conditions": [
    {
      "type": "count_gte",
      "field": "$.sources_checked",
      "value": 5
    }
  ]
}

Predicate hash:4a75acca90ed789aea7ad1c19e8f75935d5dc302db26a6a05813e87661ac8d4e

POLYMATHICA scope and limitations

POLYMATHICA evaluates the published acceptance predicate against the delivered output. It does not provide professional engineering certification.

Fuzzy name matching only -- not a legal sanctions-compliance determination or a substitute for professional KYC/AML review.
A 'clear' result means no fuzzy match above threshold across these 5 sources as of the retrieval date, not a guarantee the subject is unsanctioned or not a PEP.
PEP coverage is Wikidata-derived, scoped to current direct-subclass heads of state/government/ministers (documented judgment call, see scripts/harvest_wikidata_pep.py) -- not a comprehensive commercial PEP database.
EU/UK/UN sanctions source licence terms are not explicitly confirmed (kept 'unknown' rather than assumed) -- same treatment already established for the OFAC SDN source.

Integration

https://api.macaroonnetwork.com/execute/sanctions-pep-screening-v1

First fetch the HTTP 402 payment requirements. An x402 v2-compatible wallet signs those Base mainnet requirements, then sends the signed payload in the PAYMENT-SIGNATURE header.

# 1. Receive HTTP 402 + PAYMENT-REQUIRED
curl -i https://api.macaroonnetwork.com/execute/sanctions-pep-screening-v1

# 2. Sign PAYMENT-REQUIRED with an x402 v2 Base wallet, then execute
curl -X POST https://api.macaroonnetwork.com/execute/sanctions-pep-screening-v1 \
  -H "PAYMENT-SIGNATURE: <base64 x402 v2 signed payment payload>" \
