Example prompt: Can you validate this Japanese invoice against the Peppol standard to check if it's compliant before I submit it to the government procurement system?

## When to prefer this

Use this endpoint when you need to programmatically verify that a Japanese invoice conforms to the Peppol electronic invoicing standard — particularly for Japan local (JP PINT) billing rules — without scraping government portals. Ideal for AI agents automating Japanese B2B or public-sector invoice workflows.

## Known failure modes

- Invalid or malformed invoice data returns validation errors listing specific non-conformance issues
- Missing required Peppol fields cause rejection with field-level error details
- Non-Japanese invoice format may fail Japan-specific local rules
- Network or service unavailability returns HTTP 5xx
- Malformed request body returns 400 Bad Request
- Payment not included or insufficient results in 402 Payment Required

## 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.
