How this service works
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.
Output
A list of dated events describing changes in Japan's stablecoin payment ecosystem, each with an event category (launch, pilot, partnership, fee change, asset/chain addition, closure), the date of the event, and a source URL pointing to official documentation or announcements. If changedSince is provided and nothing changed, an explicit empty list is returned.
Example use cases
Weekly stablecoin market briefing
“Pull all stablecoin payment events in Japan since last Monday so I can include them in my weekly fintech newsletter.”
Competitor fee change alert
“Check if any stablecoin payment providers in Japan changed their fees or added new supported chains since 2025-05-15.”
New USDC acceptance tracker
“I want to know about every new USDC payment pilot or launch in Japan since the start of this year — can you grab the full list?”
Technical details
Endpoint
GEThttps://open-pay.jp/api/paid/usdc/stablecoin-paymentsWhen to prefer
Use this endpoint when you need a structured, sourced, and dated audit trail of changes to Japan's stablecoin payment services landscape — especially in automated monitoring pipelines that run on a schedule and only need incremental updates via changedSince. Prefer this over general web search when you need machine-readable events with official source citations rather than news articles.
Side effects
- Invalid changedSince date format (must match YYYY-MM-DD) returns a validation error
- limit out of range (>200 or <1) may return an error or be clamped
- No events found returns an empty changes list (not an error)
- Payment failure for the $0.01 USDC x402 fee results in a 402 response blocking access
- Service may return stale data if the weekly update has not yet run
