## 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-local-pack-api-houjin-number-lookup-38e9cc89
```

Example prompt: Can you look up the Japanese company registered under corporate number 7010001077878 — I need its official name, furigana, registered address, and whether it's still active?

## When to prefer this

Use this endpoint when you need authoritative Japanese corporate registry data (official name, address, status) for a known 13-digit houjin number, especially in office automation, invoice validation, compliance, or KYC workflows targeting Japan. Prefer this over general web search when structured, machine-readable output from the official METI source is required.

## Known failure modes

- Invalid or non-13-digit corporate number returns an error
- Corporate number not found in gBizINFO returns empty or error response
- Missing x402 payment header returns HTTP 402 with a shape preview (placeholder data, not real values)
- Network or upstream gBizINFO outage may cause failures or stale data
