How this service works

Japanese billing-invoice OCR with deterministic local checks for dates, T-number format/checksum, tax, arithmetic, and required fields. Supports text, HTTPS URL, Base64, PDF, HEIF, and TIFF. No registry lookup; use extract-and-verify for issuer comparison. / 日本語請求書OCR。日付、T番号形式・チェックサム、税額、金額整合性、必須項目をローカル検証します。text、HTTPS URL、Base64、PDF、HEIF、TIFFに対応。法人照合はextract-and-verifyを使用します。

Output

A structured JSON response containing all extracted invoice fields (issuer name, date, line items, subtotals, tax amounts, total) alongside deterministic local validation results for each checked dimension: date validity, T-number format and checksum pass/fail, tax amount correctness, arithmetic consistency of amounts, and presence of required fields. No NTA registry lookup is performed; issuer identity comparison requires a separate extract-and-verify call.

Example use cases

Accounts payable invoice intake

“We just received a Japanese supplier invoice as a PDF. Can you OCR it and check that the T-number format is correct, the tax arithmetic adds up, and all required fields like date and issuer name are present? The file is at https://storage.example.com/supplier-invoice-july.pdf”

Automated invoice compliance screening

“I have a Base64-encoded HEIF image of a Japanese billing invoice. Please extract all the invoice data and run the local validation — flag any issues with the date format, T-number checksum, or missing required fields.”

Pre-submission invoice audit

“Before we submit this Japanese invoice to our client, can you check it for me? It's a TIFF file at https://files.example.com/draft-invoice-2024.tiff — I want to make sure the tax amounts are arithmetically consistent and the T-number passes the checksum.”

Technical details

Endpoint

POSThttps://api.jpverify.com/jp-invoice/extract?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need fast, deterministic, offline-style validation of a Japanese billing invoice — checking T-number checksum, tax arithmetic, date formats, and required field completeness — without incurring the latency or cost of an NTA registry lookup. It is ideal for high-volume pre-screening pipelines. If you also need to confirm the issuer identity against the NTA registry, use the extract-and-verify or issuer-check sibling endpoints instead.

Side effects

Unsupported file format or corrupted image returns an error
HTTPS URL is inaccessible or returns non-200 response — URL fetch failure
Base64 payload is malformed or too large
Handwritten or low-resolution invoice may yield low OCR confidence or missing fields
Non-Japanese invoice format may produce incorrect field mapping
T-number absent from document — checksum check skipped with a flag
PDF with encrypted or password-protected content cannot be parsed
