## 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 synergy-lei-lookup-gleif-register-f204eb0a -d '<json body>'
```

Example prompt: Can you look up the GLEIF register for LEI code 5493001KJTIIGC8Y1R12 and tell me the legal entity name, status, and country of registration?

## When to prefer this

Use this endpoint when you need authoritative, deterministic GLEIF-sourced entity data — particularly for regulatory compliance, KYC/AML workflows, trade counterparty validation, or any context where verifying a company's official LEI registration status matters. Prefer this over general company-search APIs when the LEI standard is required (e.g., MiFID II, EMIR reporting). It is keyless and requires no external credentials, making it easy to invoke in agent pipelines.

## Known failure modes

- LEI not found in GLEIF register — entity may not be registered or LEI may be invalid
- Name search returns no results — legal name may differ from GLEIF-registered name
- Ambiguous name match returns many low-relevance results — use country filter to narrow
- GLEIF upstream unavailable — service returns 5xx or timeout
- page_size out of range (must be 1–20) returns validation error
- Invalid LEI format (not 20 characters, wrong checksum) may return error or empty result

## How this service works

Resolve a Legal Entity Identifier (LEI) or search legal names against the GLEIF public register (keyless deterministic lookup).

## Output

Returns GLEIF register data for the queried LEI or matched legal entity names, including the LEI code, official legal name, entity status (active/inactive/pending), jurisdiction, legal address, registration authority, and related registration metadata.
