How this service works
Observed change feed for listed x402 sellers: declared payTo changes with before/after values, other declared-terms changes (price, facilitator, fee payer), registry removals and returns, rating actions, and grade downgrades. Every response reports measured per-category coverage for the requested window.
Output
A structured feed of recent reliability events including wallet address changes, rating downgrade records with before/after scores, and listing death notices (delisted or unreachable endpoints), each with timestamps and provider identifiers.
Example use cases
Vetting providers before payment
“Before I route any payments to new MCP providers, pull the recent change feed and tell me if any of them have had wallet changes or rating downgrades in the last few days.”
Dead listing cleanup in agent config
“Check the MCPFax reliability feed for any listing deaths or delisted endpoints — I want to clean up my agent's tool list and remove anything that's gone offline.”
Daily reliability digest for dev team
“Fetch today's reliability change feed from the agentic marketplace and summarize any new rating downgrades or wallet address changes so I can brief my team on which APIs to watch.”
Technical details
Endpoint
GEThttps://mcpfax-reliability.bowling-anthony.workers.dev/payto-change-feed?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to monitor the health and trustworthiness of providers in the agentic/MCP marketplace — particularly when checking for wallet fraud signals (unexpected wallet changes), reliability drops (rating downgrades), or endpoint deaths before routing traffic or payments. Prefer this over manual provider checks when you want a consolidated, recent change feed rather than point-in-time status lookups.
Side effects
- No recent changes may return an empty feed rather than an error
- Invalid or malformed request body returns a 400 error
- Payment failure via x402 protocol returns 402 Payment Required
- Service unavailable returns 503 with Cloudflare Workers error
- Stale data if the feed has not been refreshed recently
