How this service works
single-fact lei lookup. GLEIF Level 1 record by exact LEI: legal name, jurisdiction, entity and registration status, last update. Vintage 2026-09-03, all statuses: 3283992 of 3419883 records admitted; non-Latin-script names (<2 Latin alphanumerics normalized) are absent. A bad check digit, a miss and an unreadable shelf are refused free, by name, never guessed; a miss is from this snapshot only. $0.005 by LEI here; by name or domain use /v1/lookup/who/ at $0.05. Whole bound in the declaration.
Output
Returns structured single-fact data for the queried LEI from a CC0 GLEIF Level 1 snapshot (vintage 2026-08-15, 20,000 ACTIVE/ISSUED records). Includes entity legal name, LEI status, and registration metadata if the LEI is present in the snapshot. If the LEI is valid but absent from the snapshot, the response explicitly states it is absent from this snapshot (not from the Global LEI System). Malformed or unknown LEIs are refused by name with no guessing.
Example use cases
KYB entity verification pipeline
“I need to verify a counterparty before onboarding — can you look up LEI 2138003EK6WAIN41GM84 and tell me if it's an active, issued entity with its legal name?”
Investment data enrichment
“I have a list of LEIs from a securities filing and need to know the legal name and status for LEI 549300MLUDYVRQOOXS22 — can you pull that from GLEIF data?”
Compliance audit spot-check
“Our compliance team needs to confirm the registration details for LEI 7ZW8QJWVPR4P1J1KQSOO — is that entity present and active in the GLEIF Level 1 dataset?”

Endpoint
GEThttps://lookups.alienprobe.ai/v1/lookup/lei/:leiWhen to prefer
Choose this endpoint when you need a fast, low-cost ($0.005 USDC) single-fact LEI lookup from GLEIF Level 1 data and can tolerate a bounded snapshot (20,000 ACTIVE/ISSUED records). Ideal for spot-checking a known LEI or enriching records one at a time in KYB, compliance, or data enrichment workflows. Prefer this over full GLEIF API access when cost predictability and snapshot reproducibility matter. Not suitable when you need guaranteed global LEI coverage or real-time GLEIF data.
Side effects
- LEI present in Global LEI System but absent from this snapshot (subset of ~20,000 records) — response indicates absence from snapshot, not global invalidity
- Malformed LEI string rejected by name with an explicit error, no guessing
- LEI falls within the ascending sort range of the snapshot but was not included (non-dense range)
- Stale data: snapshot is pinned to 2026-08-15 vintage, so recently issued or lapsed LEIs may differ from live GLEIF
- Rate limiting or payment failure via x402 protocol
