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.

JPYC Service Monitor: weekly change feed for Japan-related JPYC and Web3 services. Each event is dated, typed (added / updated / removed / verified) and tied to an official source URL. Call with changedSince=YYYY-MM-DD set to your last run date to fetch only what changed; an empty changes list explicitly means no change, so a scheduled agent can report that without guessing. Without changedSince you get the full monitor snapshot.
