## 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 japan-agent-corporate-name-search-gleif-lei-japan-nta-registry-be34a594
```

Example prompt: Can you search the GLEIF LEI database for companies named 'Toyota Motor' and return up to 5 results with their LEIs and registered addresses?

## When to prefer this

Use this endpoint when you need to identify or verify a company's official legal name, LEI, or corporate registration number from a partial or full name string. Ideal for KYB workflows, counterparty due diligence, and onboarding checks. Prefer the 'lei' jurisdiction for global coverage and the 'jp' jurisdiction for Japan-specific registry lookups via NTA. This is a search/discovery primitive — use the sibling LEI-by-ID or company enrichment endpoints once you have a specific LEI to fetch full entity details.

## Known failure modes

- No matching companies found for the given name — returns empty results list
- Invalid jurisdiction value (not 'lei' or 'jp') — returns validation error
- Name query too short or too generic — may return truncated or noisy results up to the limit
- NTA or GLEIF upstream API unavailable — returns upstream error or timeout
- Missing required 'name' query parameter — returns 400 bad request

## How this service works

Company name search across jurisdictions. jurisdiction=lei searches the global GLEIF LEI database (all countries); jurisdiction=jp searches the official Japan National Tax Agency corporate registry. Returns registered legal names, identifiers, and addresses. KYB / counterparty verification primitive.

## Output

A list of up to 50 matching legal entities (default 10), each with the registered legal name, LEI or corporate number, jurisdiction, and registered address — sourced from the GLEIF global database or Japan NTA registry depending on the selected jurisdiction.
