## 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 lilambd-japan-municipalities-data-c72b5304
```

Example prompt: Can you pull the data for Japanese municipality code 13101 — and if you can filter it to just the population indicator, that would be great.

## When to prefer this

Use this endpoint when you need structured, per-indicator statistical data for a specific Japanese municipality and you already know its numeric code. It is well-suited for research, data enrichment, and comparative analysis tasks involving Japanese local government data. Prefer this over general web search when you need machine-readable, attributed data records rather than prose descriptions.

## Known failure modes

- Invalid or unknown municipality code returns empty data array with count 0
- Missing required code path parameter results in a 400 or routing error
- Unsupported indicator name silently returns empty results
- Network or payment failure (402) if USDC payment header is not provided
- Rate limiting or service unavailability returns 5xx error

## 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 containing a data array of records for the specified municipality, a count of records returned, and an attribution string citing the data source licence. Optionally filtered to a single indicator if the indicator query parameter is provided.
