## 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-prefecture-health-data-api-da6350fe
```

Example prompt: Can you pull up the health data for all Japanese prefectures so I can compare regional health statistics across Japan?

## When to prefer this

Use this endpoint when you need prefecture-level health data specifically for Japan and are operating in an x402 micropayment environment. It is a low-cost ($0.005 per call) lookup suitable for occasional queries or research tasks where Japanese regional health statistics are needed.

## Known failure modes

- Invalid or unrecognized query parameters may return empty results or errors
- Payment failure (402) if USDC micropayment of $0.005 is not properly attached
- Rate limiting if too many requests are sent in quick succession
- Sparse or incomplete health data for certain prefectures
- Ambiguous schema means exact fields returned are unpredictable
