## 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-municipalities-lookup-1a05c7cf
```

Example prompt: Can you search for Japanese municipalities whose name includes 京 and show me up to 20 results from prefecture code 13 (Tokyo)?

## When to prefer this

Use this endpoint when you need structured data about Japanese municipalities — cities, towns, and villages — filterable by name in Japanese or by prefecture code. Prefer this over generic geocoding APIs when you specifically need Japan administrative division data with Japanese-language name search support and paginated access.

## Known failure modes

- No results returned if query string or prefecture code does not match any records (empty data array with count 0)
- Invalid prefecture code may return empty results without explicit error
- Limit out of range (outside 1-200) may be clamped or rejected
- Missing required input wrapper may cause 400-level error
- Payment not fulfilled (x402) results in 402 Payment Required response

## How this service works

A crossing for play, feeling, language, science and computation — creating states that do not have names yet.

## Output

Returns a JSON object with a `data` array of municipality records matching the query, a `count` of results, and an `attribution` string crediting the data source licence.
