Output
A JSON object containing the Peppol validation outcome for the submitted invoice, including pass/fail status, a list of any conformance errors or warnings, and details on which Peppol rules were checked against Japanese requirements.
Example use cases
Bulk invoice compliance before supplier payment
“We're processing a batch of invoices from our Japanese suppliers this week. Can you validate each one against the Peppol standard so we know which ones are ready to submit to the e-invoicing network and which ones need corrections first?”
Pre-submission audit for tax authority filing
“I'm about to register our company's invoices with the Japan Digital Agency system. Can you run a compliance check on all our recent invoices to make sure they meet the Peppol e-invoice format requirements before I submit them?”
Trading partner format verification workflow
“Our Japanese business partners are asking us to confirm our invoices are valid for their Peppol network. Can you validate our invoice format against the Japanese Peppol standard and give me a compliance report I can share with them?”
Technical details
Endpoint
POSThttps://kasanegi.com/v1/local/invoice/peppol-validateWhen to prefer
Use this endpoint when you need to validate Japanese business invoices against the Peppol e-invoicing standard before submitting them to the Japan Digital Agency's invoice registration system or trading partners. Prefer this over manual scraping of Japanese government validation portals or building your own Peppol schema validator, especially in automated agent workflows that process invoices at scale.
Side effects
- Invalid or malformed invoice data returns a 400-level error with details
- Missing required invoice properties causes validation to fail with error list
- Network or upstream API unavailability returns 5xx error
- Non-Peppol or unrecognized invoice format may return an unsupported format error
- Payment not provided or insufficient USDC balance causes 402 payment required
