How this service works
Reliability layer for x402 data providers. Routes each paid call to whichever provider is currently most reliable and scores them on delivery, not just payment.
Output
Returns the response data from the winning provider, a single-use receipt UUID (usable to POST /review), the ID of the provider that handled the request, latency in milliseconds, an ordered list of any providers that failed over, and a category Merkle root hash for verifiable categorization.
Example use cases
Resilient quote data fetching
“Fetch me a quote using the most reliable x402 provider available — I need JSON body, HTTP POST, and if the first provider fails I want it to automatically try the next best one.”
Debugging provider reliability
“Send this paid data request through the reliability router and tell me which provider handled it, how long it took, and whether any failovers happened.”
Auditable paid API call
“Make a reliability-routed x402 call for this quote endpoint and give me back the receipt UUID so I can use it to post a review afterward.”
Technical details
Endpoint
POSThttps://200.surfacedplus.com/route/example.quote?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need resilient, production-grade access to x402 data providers and cannot tolerate silent failures. It is preferable over calling a single x402 provider directly when uptime matters, when you want auditable receipts for provider reviews, or when you want to let scoring/routing logic handle provider selection rather than hard-coding a single endpoint. Especially useful when operating in adversarial or unreliable provider environments.
Side effects
- All providers in the pool fail — returns empty failedOver list with error state
- Invalid input schema (missing required fields: type, method, bodyType, body) — likely 400-level error
- Payment not processed — x402 payment failure before routing occurs
- Provider responds but with incorrect or empty data — may still return routedTo but data field is empty
- Timeout on all providers — latencyMs may be high with populated failedOver array
