JPYC Service Monitor
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.
