## 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-business-signals-by-houjin-number-101741bf
```

Example prompt: Can you pull all available business signals for Japanese company with houjin number 1234567890123 — I need gBizINFO registration details, any Kanpou gazette notices, and EDINET filings for supplier due diligence.

## When to prefer this

Use this endpoint when you need to enrich a Japanese corporate entity using its official 13-digit houjin (corporate) number and want aggregated signals from multiple authoritative Japanese government sources (gBizINFO, Kanpou, EDINET). Prefer this over generic business data providers when the target company is Japanese and you need government-sourced KYB, supplier research, or B2B sales intelligence data. Especially useful for AI agents performing automated due diligence on Japanese counterparties without needing a pre-registered API key.

## Known failure modes

- Invalid or malformed houjin number returns 400 or error response
- Houjin number not found in any source returns empty or null signals
- Payment failure via x402 micropayment results in 402 Payment Required
- Rate limiting or worker timeout returns 5xx error
- EDINET or gBizINFO upstream source temporarily unavailable causes partial data return
