## 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 denpyo-japan-invoice-receipt-ocr-qualified-invoice-verifier-3a1c99fe -d '<json body>'
```

Example prompt: I have a photo of a receipt from セブン-イレブン — can you extract all the line items, totals, and 8%/10% tax split from it, and verify that the qualified invoice registration number (T番号) is active in the National Tax Agency registry?

## When to prefer this

Choose this endpoint when you need to process Japanese-language invoices or receipts and require both structured data extraction AND real-time qualified invoice (適格請求書) number verification against the NTA registry in a single API call. It is especially suitable for AP automation pipelines, expense processing systems, and pre-payment fraud checks that must confirm a Japanese supplier's tax registration status without managing separate OCR and verification services. It is not suitable for non-Japanese documents or for cases where only the T番号 needs to be verified without an accompanying document image.

## Known failure modes

- Blurry or low-resolution image may result in extraction errors or missing fields
- Registration number not found in NTA registry returns unqualified verdict
- Non-Japanese invoices or receipts will not parse correctly
- Handwritten documents may have lower extraction accuracy
- Insufficient USDC balance or payment failure via x402 returns a payment-required error
- Malformed or missing T番号 on the document results in null registration number and no verification

## How this service works

Japanese receipt (領収書/レシート) → normalized JSON + qualified-invoice verification in one call. OCR: merchant, date & time, items, totals and the 8%/10% consumption-tax breakdown. The registration number (T+13 digits) is extracted and verified against the National Tax Agency registry, so an expense agent knows instantly whether the receipt supports input-tax credit (仕入税額控除). Send {"url"} or {"base64"} (photo or PDF). First page. Failed analyses are not charged.

## Output

A JSON object containing: document type (invoice or receipt), merchant info (name, address, phone, registration number), transaction date and time, line items with descriptions and prices, amounts (subtotal, tax, total in JPY) with a per-rate tax breakdown (8% and 10% buckets), pages processed, and a qualifiedInvoice block with the T番号, its NTA registry status (active/cancelled), and a verdict (qualified/unqualified).
