How this service works
Pay-per-request governance APIs for AI agents using x402. Check budgets, log payments, classify invoices, and generate audit-ready spending records. Built for autonomous agents, USDC/Base payments, and JPY/JPYC reporting workflows.
Output
Returns a classification of the transaction's status under Japan's qualified invoice (Tekikaku Seikyusho) system, indicating tax eligibility, whether the buyer can claim an input tax credit, and the applicable consumption tax treatment based on seller registration status and transaction parameters.
Example use cases
Example prompt
“Classify this invoice: the transaction date is 2024-11-15, the seller is invoice registered, the total amount including tax is 110,000 JPY, and our company's annual taxable sales are 50,000,000 JPY — tell me if this qualifies under Japan's invoice system.”
Technical details
Endpoint
POSThttps://agent-budget-guard.onrender.com/api/classify-invoiceWhen to prefer
Use this endpoint when you need to programmatically classify Japanese business invoices for consumption tax compliance, particularly for autonomous agents handling JPY or JPYC-denominated transactions that must generate audit-ready records. Ideal for workflows involving Japanese B2B procurement, expense reporting, or tax credit validation where the qualified invoice system (Tekikaku Seikyusho) applies.
Side effects
- Missing required fields (transaction_date, buyer_taxable_sales_jpy, seller_invoice_registered, transaction_amount_tax_included_jpy) result in validation error
- Invalid date format (not YYYY-MM-DD) causes parsing failure
- Non-numeric JPY amount strings may cause computation errors
- Payment failure via x402 (insufficient USDC balance) blocks the request
- Seller registration status value not recognized causes classification to fail
