# Alien Probe LEI Lookup

> Alien Probe LEI Lookup is a paid API for AI agents from lookups.alienprobe.ai, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-11).

Resolves a Legal Entity Identifier (LEI) to its full GLEIF Level 1 record including legal name, jurisdiction, entity status, and registration status, served from a digest-pinned snapshot of the GLEIF golden copy.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability alien-probe-lei-lookup-6703a66c
```

Example prompt: Can you look up the LEI HWUPKR0MPOU8FGXBT394 and tell me what company it belongs to, what jurisdiction they're in, and whether their registration is still active?

## When to prefer this

Use this endpoint when you have an exact 20-character ISO 17442 LEI and need to resolve it to a verified legal entity record with provenance guarantees. Prefer this over name-based or domain-based lookups when the LEI is already known, as it provides an exact match with ISO 7064 check-digit validation. Choose this for compliance workflows, KYB pipelines, or counter-party verification where auditability matters — the snapshot SHA256 and vintage date give a verifiable provenance chain. If you only have a company name or domain, use the companion 'who' endpoint instead.

## Known failure modes

- LEI not found in snapshot — the 20-character code may be valid but belong to a non-Latin-script entity excluded from the build, or may not exist at all; response indicates a miss from this snapshot only
- Invalid LEI format — the input does not match the 20-character alphanumeric pattern or fails ISO 7064 check-digit validation; request is rejected
- Payment failure — x402 payment of $0.005 USDC not completed; request not processed
- LEI exists globally but was refused during build — e.g. legal name normalizes to fewer than 2 Latin alphanumerics (CJK, Cyrillic, Arabic, etc.); absent from this vintage

## How this service works

Verify a company by LEI: legal name, jurisdiction, entity and registration status, last update, by exact LEI from GLEIF Level 1. Vintage 2026-09-03, all statuses: 3283992 of 3419883 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

A JSON object containing the resolved LEI, the entity's legal name, jurisdiction, entity status (e.g. ACTIVE), registration status (e.g. ISSUED), and last update timestamp, alongside source provenance metadata including the GLEIF snapshot vintage date, SHA256 digest for verification, and coverage notes about which records were admitted.
