## 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-c5ea10d9 -d '<json body>'
```

Example prompt: Can you look up the legal entity name, jurisdiction, and registration status for LEI 5493001KJTIIGC8Y1R12 using the GLEIF reference data?

## When to prefer this

Use this endpoint when you need authoritative, current legal entity information from GLEIF for a known LEI code — especially in compliance, KYC, counterparty verification, or data enrichment workflows where official registration status and jurisdiction matter. Prefer this over name-search endpoints when you already have the LEI and need to resolve it to structured entity data.

## Known failure modes

- Invalid LEI format (not matching 18 alphanumeric + 2 digit pattern) returns a validation error
- LEI not found in GLEIF registry returns an empty normalized result
- Network or upstream GLEIF API unavailability may cause retrieval failure
- Stale or cached data if cache age approaches maximum cache seconds (60s)

## How this service works

Pay-per-request evidence and data tools: CSV validation and reconciliation, DNS/email configuration evidence, and bounded official weather, earthquake, vehicle, company and study records. Exact USDC prices, explicit JSON contracts and source provenance. No mailbox, ownership, medical or safety guarantees.

## Output

Returns a JSON object containing the queried LEI, the normalized legal entity name, jurisdiction, registration status, renewal/expiry dates, and GLEIF source metadata including data freshness, provenance, license (CC0 1.0), and the upstream GLEIF API reference URL.
