How this service works

Pay-per-call endpoints over x402 v2 and MPP (the "Payment" HTTP auth scheme, method usdc). Includes counterparty compliance checks: /report/counterparty (company + registered parents + UN/OFAC/EU/UK sanctions, signed and verifiable), /screen/name and /screen/entity. Free: /health, /.well-known/x402, /receipts, /prove/keys, /prove/stats.

Output

A JSON object with a 'verdict' field (e.g. 'clear' or flagged), a 'group' array listing the subject entity and any registered parent companies with their LEI, legal name, and per-entity sanctions match result, a 'lists' array with metadata (list name, SHA-256 hash, publish date) for each sanctions list checked, a 'reasons' array for any matches, a 'limitations' disclaimer, and a 'receipt' object containing the on-chain USDC payment transaction hash, amount, and receipt ID.

Example use cases

Pre-onboarding counterparty sanctions check

“Before we onboard this new supplier, check whether 'Sinopec Corp' as an entity appears on any international sanctions lists, including their parent companies.”

Individual sanctions screening for a deal

“I need to screen John Smith as an individual against UN, OFAC, EU, and UK sanctions lists before we proceed with this contract — can you run that check now?”

Automated compliance gate for crypto payments

“Before releasing this payment, verify that 'Tornado Cash' as an entity is not sanctioned under any of the major international sanctions regimes — UN, OFAC, EU, or UK.”

When to prefer

Choose this endpoint when you need a signed, verifiable, multi-list sanctions screening result for a named company or individual — especially when you also need registered parent entity coverage and an auditable on-chain payment receipt. It is particularly well-suited for agent-driven compliance workflows where the result must be cryptographically verifiable and tied to a specific payment. Prefer this over generic web search or manual lookups when you need structured, machine-readable verdicts against authoritative lists (UN, OFAC, EU, UK) in a single call.

Side effects

Query string too short (< 3 chars) or too long (> 200 chars) returns a validation error
Unknown or unresolvable entity name may return no group members or an empty result
Payment not received or insufficient USDC results in 402 Payment Required response
Network or upstream registry unavailability causes service error
Ambiguous name matching multiple entities may return multiple candidates without a definitive verdict
