How this service works
KYB entity diligence pack — OFAC SDN fuzzy screen + GLEIF LEI match/resolve in one agent JSON. Directional only; not clearance.
Output
Returns a JSON object with an 'ofac' block containing fuzzy-matched SDN hits and hit count, a 'gleif' block with LEI match results and resolved entity record, list freshness timestamps for both OFAC and GLEIF, and prominent disclaimers that results are directional only and not clearance or attestation.
Example use cases
Vendor onboarding sanctions check
“Before we onboard this new supplier, can you screen 'Global Freight Partners Ltd' against OFAC sanctions and pull their GLEIF LEI info? Use a match threshold of 0.65 and return up to 20 hits.”
Unknown counterparty LEI resolution
“I have an LEI of 'HWUPKR0MPOU8FGXBT394' for a company called 'EuroCargo Solutions' — can you resolve that LEI and check if they appear on the OFAC SDN list?”
Quick compliance pre-screen for investment
“We're considering an investment in 'Meridian Capital Holdings' — can you do a quick OFAC fuzzy screen and GLEIF lookup on them before we go further, with a threshold of 0.55?”
Technical details
Endpoint
POSThttps://x402-kyb-api.vercel.app/api/v1/kyb/pack?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined OFAC SDN fuzzy screen plus GLEIF LEI lookup in a single API call, especially for lightweight KYB pre-screening in an agentic workflow. Prefer this over separate OFAC or GLEIF APIs when you want a fast, unified diligence signal at low cost ($1 USDC per call). Not suitable as a replacement for formal compliance clearance, certified OFAC screening, or legal attestation.
Side effects
- Missing required 'name' field returns validation error
- LEI format invalid (not 20 characters) may cause GLEIF resolution failure
- Threshold outside 0-1 range returns error
- Limit exceeding 50 rejected
- Network or upstream OFAC/GLEIF data source unavailable returns 5xx
- Payment not provided or insufficient returns 402 Payment Required
- False positives and false negatives possible by design — flagged in response banner
