open-pay.jp
https://open-pay.jp/api/paid/usdc/jpyc/activityShares a payout wallet with 13 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.
JPYC transfer metrics computed hourly from finalized Polygon blocks: event count, unique senders and receivers, volume, median and top receivers. Covers approximately 24 hours ending at the newest finalized hourly bucket; exact block and time range are in the response. Use for current JPYC usage metrics; not for wallet balances, price, news, supply or financial advice.

How often it was reachable when we probed it (weight 35%).
How quickly it answers when it is up — fast scores high (weight 20%).
Whether it serves over working TLS / https (weight 15%).
Whether the operator disclosed what it does — description, schema, identity (weight 15%).
Observed on-chain payments to this endpoint's wallet — transactions, volume, and distinct paying wallets over the last month (weight 15%; not yet measured when we have not seen its wallet settle).
Confidence 100% — how much probe evidence backs this score. A thin history is flagged, not hidden.
See the scoring methodology for exactly how each number is computed.

Operator context is derived from public RDAP/TLS records and unverified. Company and country are only available for endpoints that publish them (an OV/EV TLS certificate or a non-redacted domain record); most endpoints are CDN-fronted and disclose neither.

This payout wallet is shared: figures cover all 14 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.
Linked by wallet — likely same operator
On-chain agent identity and the x402 endpoint that shares its settlement wallet.
