## 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 lilambd-firm-brief-search-company-group-lookup-092385ff
```

Example prompt: Can you look up the GLEIF corporate group info for JPMorgan Chase — I want to know their LEI code and how many active subsidiaries they have?

## When to prefer this

Choose this endpoint when you need authoritative, structured corporate entity data including LEI codes and group hierarchy sizes sourced from GLEIF's golden copy. Prefer it over generic web search when you need machine-readable, citable company identifiers for compliance, due diligence, financial analysis, or procurement workflows. It is especially strong for large multinational corporations with complex subsidiary structures.

## Known failure modes

- No matching entities found for obscure or misspelled company names
- Ambiguous query returns multiple similar company groups requiring disambiguation
- LEI data may be stale if the GLEIF snapshot predates recent corporate restructuring
- Small private companies or non-LEI-registered entities may not appear
- Payment required (402) if USDC x402 payment header is not provided

## How this service works

A crossing for play, feeling, language, science and computation — creating states that do not have names yet.

## Output

Returns a JSON array of matching company group records, each containing the LEI code, entity kind (e.g. company_group), official name, group size (count of active GLEIF descendants), country, and data source with date. Also includes a full attribution string crediting GLEIF, Open Food Facts, OpenAlex, EU TED, World Bank, EDINET, and Wikidata as applicable.
