How this service works
Pay-per-call KYB pack: OFAC SDN screen + GLEIF LEI match/resolve (USDC on Base + Solana via x402). Directional only — not clearance.
Output
Returns a JSON object containing: OFAC SDN screening results (list of hits with match scores, hit count, and whether results are potential matches only), GLEIF LEI match results (list of matched LEIs and hit count) and optionally a resolved LEI record, timestamps indicating how fresh each list is, and a prominent banner clarifying the result is directional only and not a formal clearance or attestation.
Example use cases
Onboarding vendor sanctions screen
“Before we onboard this new supplier, can you screen 'Bright Horizon Logistics LLC' against the OFAC SDN list and pull their GLEIF LEI match so I can review the diligence pack?”
Counterparty LEI resolution by name
“I have a counterparty called 'Deutsche Finanz AG' but I don't have their LEI — can you look them up in GLEIF and also run a quick OFAC check while you're at it?”
High-confidence sanctions check with known LEI
“We already have the LEI '5493001KJTIIGC8Y1R12' for this entity — can you resolve it in GLEIF and do an OFAC SDN screen with a strict threshold of 0.8, returning up to 20 hits?”
Technical details
Endpoint
POSThttps://x402-kyb-api.vercel.app/kyb?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined OFAC SDN screen and GLEIF LEI lookup in a single pay-per-call API call without committing to a subscription. It is ideal for agents that handle infrequent or on-demand KYB checks and can pay per call in USDC via x402 on Base or Solana. Prefer alternatives when you need formal clearance letters, certified attestations, full AML reports, or continuous monitoring — this endpoint is explicitly directional and not a substitute for regulated compliance clearance.
Side effects
- Missing required 'name' field returns a validation error
- Threshold outside 0-1 range may cause a bad request error
- Network or upstream OFAC/GLEIF data source unavailability returns a 5xx error
- Payment not completed via x402 protocol results in a 402 Payment Required response
- Invalid LEI format (not 20 chars) may cause GLEIF resolution to fail or return no match
- Empty name string may return zero hits without error
