## 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`):

Example prompt: Can you look up the legal name, jurisdiction, and registration status for LEI code 549300MLUDYVRQOOXS22?

## When to prefer this

Use this endpoint when you need deterministic, keyless GLEIF-sourced LEI resolution without managing API keys — ideal for compliance workflows, counterparty verification, KYC enrichment, or any scenario requiring official legal entity details from an LEI code. Prefer this over direct GLEIF API calls when you want a simple POST interface with per-call micropayment pricing.

## Known failure modes

- Invalid LEI format returns an error
- LEI not found in GLEIF registry returns empty or not-found response
- Upstream GLEIF API failure returns no charge and an error indicator
- Missing or malformed X-WALLET header may result in billing errors after free tier is exhausted
