How this service works
Japan payroll / tax / social insurance / mynumber / corporate / invoice / holiday reference API for AI agents. x402 micropayments on Base. No API key.
Output
A JSON object containing the standard consumption tax percentage (e.g. 10%), the reduced consumption tax percentage (e.g. 8%), a flag indicating whether Japan's qualified invoice system is active, the date it became active, the date the current rates became effective, and a summary of which items qualify for the reduced rate.
Example use cases
Verify invoice system activation date
“Can you confirm when Japan's qualified invoice system officially became active, and is it currently in effect for invoices I'm issuing today?”
Apply correct VAT to food items
“I'm building an invoice for a Japanese customer that includes food and beverages — what consumption tax rate should I apply to those items, and are there any exceptions I should know about?”
Look up historical Japan tax rates
“What were Japan's standard and reduced consumption tax rates back in October 2019, and was the qualified invoice system active at that time?”
