## 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-search-global-legal-entity-identifier-lookup-7d7b0b0b -d '<json body>'
```

Example prompt: Search the GLEIF LEI index for 'Skoda Auto' and give me the LEI code, entity status, and registration status.

## When to prefer this

Use this endpoint when you need authoritative, deterministic LEI data sourced directly from the GLEIF Global LEI Index without AI inference or web scraping. Prefer it over general web search when you need machine-readable LEI codes for compliance, KYC, or financial onboarding workflows. Ideal when the company could be Czech, European, or globally registered. Pay-per-call pricing at $0.002 USDC means zero cost for not-found or upstream-error results.

## Known failure modes

- Company name not found in GLEIF index — no results array, not charged
- GLEIF upstream timeout or 5xx error — request not charged
- Ambiguous company name returns multiple results requiring disambiguation
- Non-Latin or special characters in company name may reduce match quality
- Very new or recently dissolved entities may not appear in GLEIF index

## How this service works

Deterministic lookups from official public sources (ARES, EU VIES, Czech National Bank, GLEIF LEI index). No AI, no scraping. Pay per call in USDC on Base via x402. Requests that fail upstream (5xx/timeout) or not-found results are not charged.

## Output

Returns a JSON object with the search query, total result count, data source attribution (GLEIF, CC0 licensed), country filter, and an array of matching entities each containing LEI code, company name, city, country code, entity status (e.g. ACTIVE), and registration status (e.g. ISSUED).
