How this service works
Where JPYC (Japan's yen-pegged stablecoin) is accepted: curated exchanges, DEXes, dApps and bridges as JSON, each with category, supported assets and an official URL.
Output
Returns a list of merchant/store records registered on the OpenPay platform, including details about each store such as name, accepted currencies (JPYC, USDC), payment methods (QR, mobile order), and relevant merchant metadata needed for initiating payments or orders.
Example use cases
AI agent pays at local cafe
“I want my agent to find a coffee shop in Japan that accepts USDC via OpenPay so it can place a mobile order for me — what stores are available?”
Tourist finding crypto-friendly stores
“I'm in Japan and I only have JPYC stablecoins — can you find me shops or restaurants registered on OpenPay where I can pay with a QR code?”
Developer testing OpenPay integration
“Pull the full list of stores on the OpenPay network so I can check which merchants are live and accepting USDC payments before I demo my AI agent ordering flow.”
Technical details
Endpoint
GEThttps://open-pay.jp/api/paid/usdc/storesWhen to prefer
Choose this endpoint when an AI agent or application needs to discover merchants in Japan that are integrated with the OpenPay stablecoin payment infrastructure, particularly when the use case involves JPYC or USDC payments, QR-based checkout, or mobile ordering. It is the right choice for building agent-driven purchasing flows, tourist crypto-payment apps, or developer integrations testing OpenPay merchant coverage.

- API may return empty list if no stores are currently active
- Network timeout or service unavailability given infrastructure is small/open-source
