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 with an OFAC block (hits array, hit count, potential_matches_only flag), a GLEIF block (matched LEIs and resolved LEI details), list freshness timestamps for both OFAC and GLEIF, a banner warning that results are directional only and not formal clearance or attestation, and flags for not_clearance and not_attestation.
Example use cases
Vendor onboarding sanctions check
“Before we onboard this new supplier, can you screen 'Meridian Exports LLC' against OFAC and pull their GLEIF record? Their LEI is 5493001KJTIIGC8Y1R12, and use a match threshold of 0.65 with up to 15 hits.”
Counterparty risk check for a deal
“We're about to sign a deal with 'Russo-Baltic Capital Partners' — can you run them through OFAC SDN screening and see if there's a GLEIF match? Limit results to 20 hits and use the default threshold.”
Automated KYB for new account opening
“A new business account just applied under the name 'Global Horizons Trading Co.' — can you run the KYB diligence pack on them, screen OFAC, and check GLEIF, with a threshold of 0.7 and max 10 hits?”
Technical details
Endpoint
POSThttps://x402-kyb-api.vercel.app/kyb/pack?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap, pay-per-call directional KYB signal combining OFAC SDN screening and GLEIF LEI resolution in a single round-trip — especially in agentic workflows where formal clearance is handled downstream and you want a first-pass filter before committing to deeper due diligence. Prefer it over full KYC/AML platforms when cost-per-call and ease of integration matter more than formal regulatory attestation.
Side effects
- Missing required 'name' field returns a validation error
- LEI not found in GLEIF registry returns found:false with empty resolve block
- OFAC list temporarily unavailable may cause degraded or error response
- Threshold set outside 0-1 range likely returns a validation error
- Payment not processed via x402 returns 402 Payment Required before any results
- Very high match thresholds (near 1.0) may produce zero hits even for real entities
