## 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 jp-data-enrich-api-japan-corporate-enrichment-by-domain-92017b03
```

Example prompt: Can you pull the corporate profile for the Japanese company at the domain toyota.co.jp — I need their registration info, any EDINET filings, and official gazette data for supplier due diligence.

## When to prefer this

Use this endpoint when you need to look up Japanese corporate data for a specific company identified by its domain, especially for B2B sales prospecting, KYB compliance checks, or supplier vetting workflows targeting Japan-based entities. Prefer this over general web search when you need structured, authoritative registry data aggregated from official Japanese government sources like gBizINFO, EDINET, and Kanpou.

## Known failure modes

- Domain not found in any aggregated registry — returns empty or null corporate data
- Domain resolves to a non-Japanese company — may return no results
- Rate limiting or payment failure via x402 micropayment on Base — returns 402 Payment Required
- Malformed domain input — returns 400 Bad Request
- Upstream registry (gBizINFO/EDINET/Kanpou) unavailable — returns 503 or partial data
