## 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-e-gov-law-article-keyword-search-1164a565
```

Example prompt: Search Japan's e-Gov law database for articles mentioning 'personal information' and return up to 10 results with their law titles, categories, and excerpts.

## When to prefer this

Use this endpoint when you need to identify which specific Japanese laws and articles contain a given keyword or legal term, backed by live data directly from Japan's Digital Agency e-Gov Law API v2. Prefer this over general web search when you need structured, authoritative law metadata (title, category, excerpt, source URL) rather than unstructured text. Ideal for compliance research, legal due diligence, and regulatory analysis involving Japanese law.

## Known failure modes

- Keyword not found — returns empty results list
- Keyword exceeds 100 characters — validation error
- Limit outside 1-20 range — validation error
- e-Gov upstream API unavailable — proxy returns error
- Payment not processed — 402 response before data is returned
