## 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 kasanegi-japan-public-data-batch-enrich-api-571714ec -d '<json body>'
```

Example prompt: Can you batch-enrich this list of Japanese company IDs against Kasanegi's Japan public-data API to pull back their payroll and grant information — I have about 10 companies I need structured data on so I don't have to scrape Japanese government sites myself.

## When to prefer this

Choose this endpoint when you need to enrich multiple Japanese entities at once in a single API call, avoiding repeated scraping of Japanese government and public-data websites. Ideal for bulk company research, HR/payroll analysis, or grant discovery workflows targeting Japan-specific data. Prefer over single-record endpoints when processing lists of Japanese companies or entities.

## Known failure modes

- Missing or malformed 'properties' field returns 400 validation error
- Payment not attached or insufficient USDC (x402 required at $0.05 per call) results in 402 Payment Required
- Unknown or unsupported entity identifiers return empty or partial results
- Rate limiting or quota exceeded returns 429
- Network timeout if batch is too large

## How this service works

Stop scraping Japanese government and public-data sites. Call clean Japan payroll, company, and grant APIs over one host. Preview free; one public marketplace listing covers all current products; x402 direct is available for agent-native buyers.

## Output

A JSON response containing enriched structured data for each entity in the batch, sourced from Japanese government and public-data repositories — including company details, payroll figures, and/or grant information depending on the properties requested.
