api.annalist.dev/v1/checks/changes

What changed in x402 service listings, from daily snapshots of Coinbase's Bazaar: price raises and cuts, endpoints added and dropped, new and departed services, and payout-wallet changes (worth checking before paying: a hijacked listing looks the same as a rotated wallet). Market-wide for the last 1 to 7 days, or one service's 30-day change log with host=. Signed.
