What it does

The specific capability behind this listing, and where to get it.

Scheduled watchdog for x402 sellers: polls Coinbase CDP's public Bazaar discovery catalog for your registered resources and payTo address, flagging a drop or a recovery — instead of finding out from a revenue dip days later. How it works: register a payTo address and resource URLs once; a scheduled poll diffs them against the live discovery catalog and alerts on a state change. The `check_listing_health` MCP tool runs the same scoped diff on demand, whether or not a payTo/resources pair has been registered. Free tier: 6-hour polling, drop/recovery detection with a durable alert history — no card required. Paid tiers tighten the polling interval and add escalation/rank-drop alert types.
