How this service works
OCR a Japanese invoice (請求書) into JSON — vendor, line items, 8%/10% consumption-tax (消費税) breakdown — and verify the qualified-invoice registration number (適格請求書 インボイス登録番号 / T番号, T+13 digits) against Japan's National Tax Agency (国税庁) registry in one call: qualified/cancelled, registered-name match, corporate record (法人番号). Pre-payment 経理/AP check. POST {url|base64} (PDF/JPEG/PNG). First 2 pages. Failed analyses not charged.
Output
A JSON object containing: document type (invoice/receipt), vendor details (name, address, phone, registration number), customer name, invoice metadata (ID, issue date, due date), line items (description, quantity, unit price, amount, tax rate), amounts (subtotal, tax, total, currency, per-rate tax breakdown), and a qualifiedInvoice block with NTA verification result (active/cancelled status, name match, corporate registry record, checksum validity, registration/cancellation dates, and verdict).
Example use cases
AP automation for Japanese suppliers
“I've got a batch of 請求書 PDFs from our Japanese suppliers — can you extract the vendor details, invoice dates, line items, and the consumption tax split for each one so I can post them to our accounting system?”
Pre-payment fraud check on vendor invoice
“Before we pay this invoice from a new Japanese vendor, can you verify their インボイス登録番号 T1234567890123 is genuinely active with the NTA and that the registered company name matches what's on the invoice?”
Employee expense receipt processing
“My employee submitted a stack of Japanese receipts for reimbursement — please parse each one to get the merchant name, date, total amount, and the 8%/10% tax breakdown so I can log them in our expense system.”
Technical details
Endpoint
POSThttps://denpyo-api.hp-vladic.workers.dev/read/invoiceWhen to prefer
Choose this endpoint when you need both OCR-based extraction of Japanese invoice/receipt data AND real-time NTA registry verification of the qualified-invoice number in a single call. It is purpose-built for Japan's インボイス制度 (qualified invoice system), handles the 8%/10% dual consumption-tax rate split natively, and requires no API key or subscription — ideal for per-transaction AP automation, fraud screening before payment, or expense processing pipelines that must comply with Japanese tax law.
Side effects
- Unreadable or low-quality image results in failed extraction
- T番号 not present on document — qualifiedInvoice block absent or unverified
- NTA registry lookup fails if number is malformed or checksum invalid
- Non-Japanese invoice submitted — parsing may be incomplete or incorrect
- Payment failure via x402 results in 402 response before processing begins
- Multi-page documents may return partial results if page limit exceeded
