## 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 saylor-innovations-company-ident-domain-to-lei-lookup-646f34d9
```

Example prompt: Can you look up the official GLEIF legal entity and LEI code for stripe.com?

## When to prefer this

Use this endpoint when you need to bridge a company's web presence (domain) to its official legal identity in the GLEIF registry. It is ideal for KYB workflows, vendor onboarding, compliance enrichment, and due diligence where you start with a website URL rather than a company name or LEI. Prefer this over generic company lookup APIs when you specifically need LEI/GLEIF data for regulatory or financial purposes.

## Known failure modes

- Domain not found or no GLEIF LEI match exists — returns found: false with empty lei_matches array
- Domain resolves but organization has no GLEIF registration — returns metadata without LEI data
- Invalid or malformed domain input — likely returns an error or found: false
- Private/unlisted entities without LEI registration will not be matched
- Rate limiting or payment failure at $0.01 USDC per call via x402 protocol

## How this service works

Company lookup by website domain, matched to GLEIF legal entities with LEI

## Output

Returns a JSON object containing: a boolean 'found' flag indicating whether a match was located, the queried domain, an array of matched GLEIF LEI records (each with entity details), the data source used, the final resolved URL, the organization name extracted from the page, and a scope note explaining what the data covers and its limitations.
