## How to call it through Zero

```sh
zero fetch --capability aayat-ai-lei-lookup-743743c3
```

Example prompt: Can you look up Tesco PLC in the GLEIF LEI register and tell me their LEI code, registered address, and whether their registration is active?

## When to prefer this

Use this endpoint when you need authoritative, globally standardised legal entity data from the GLEIF register — the definitive source for LEI records covering 2.9M+ companies and funds worldwide. Prefer this over general company registries when you need LEI codes specifically, cross-border entity verification, parent company chains, or when compliance with financial regulation (MiFID II, EMIR, etc.) requires an LEI. Best for KYC, counterparty due diligence, and corporate ownership research.

## Known failure modes

- No results found for the given name or LEI (empty results array with total: 0)
- Invalid or malformed LEI code returns no match
- Country code not recognized or incorrect ISO format
- Query too vague returning hundreds of results requiring further filtering
- Sole proprietor entities hidden from results per privacy rules
- Rate limiting or payment failure if USDC balance is insufficient

## How this service works

Look up legal entities in the global LEI register (GLEIF, 2.9M+ companies and funds worldwide): by LEI (with direct and ultimate parent companies), by name, or by national company number. Registered address, status, jurisdiction. Companies only.

## Output

Returns a JSON object with the total number of matches, an array of matching legal entity records (each including LEI, company name, registered address, country, jurisdiction, legal status, national company number, legal form code, creation date, registration status, last update, next renewal, and corroboration level), and for LEI lookups, a 'parents' object containing direct and ultimate parent company details. GLEIF data is provided under CC0 1.0 licence.
