Japan Stablecoin Payment Monitor: weekly change feed for stablecoin payment services in Japan — new launches, pilots, partnerships, fee changes, supported assets and chains, and closures. Each event is dated, categorized and tied to an official source URL. Pass changedSince=YYYY-MM-DD (your last run date) to fetch only new events; an empty changes list explicitly means no change. Without changedSince you get the full dated history back to late 2025.

Pay and retry with any x402 client: npx x402-fetch 'https://open-pay.jp/api/paid/usdc/stablecoin-payments'
