# GLEIF LEI Lookup

## 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 gleif-lei-lookup-54847771
```

Example prompt: Can you verify whether the LEI code 2138002658CCY52I4L80 is valid and registered in the GLEIF global register, and give me the entity details and an audit receipt?

## When to prefer this

Choose this endpoint when you need authoritative verification of an LEI against the live GLEIF register with a built-in checksum pre-filter to avoid unnecessary remote calls, plus a durable audit receipt for compliance purposes. Prefer it over manual GLEIF portal lookups in automated workflows, KYC/KYB pipelines, financial transaction counterparty checks, or any regulatory context requiring a traceable audit trail. It pairs naturally with sibling endpoints on lookups.nl for VAT and EORI validation in European compliance workflows.

## Known failure modes

- Invalid LEI format — fails local ISO 17442 checksum before hitting GLEIF (returns validation error immediately)
- LEI not found in GLEIF register — entity may have never registered or the code is incorrect
- GLEIF service temporarily unavailable — retry logic is built in but may ultimately time out
- LEI is lapsed or retired — returns record but with non-active status
- Malformed LEI string (wrong length or illegal characters) — rejected at prefilter stage

## How this service works

Look up a Legal Entity Identifier in the global GLEIF register: local ISO 17442 checksum prefilter, authoritative GLEIF check with retry and cache, durable audit receipt.

## Output

Returns structured GLEIF record data including entity name, legal address, registration status (ISSUED, LAPSED, RETIRED, etc.), registration authority, and renewal dates. Also includes a durable audit receipt confirming the check was performed, timestamp, and whether the local ISO 17442 checksum passed before the authoritative lookup.
