How this service works
MCPFax credit grade, subscores, confidence, and cited evidence
Output
Returns a structured reliability assessment including an overall credit-style grade (e.g. A, B, C), individual subscores covering dimensions of seller reliability, a confidence percentage indicating how certain the scoring model is, and cited evidence references supporting the assessment — all specific to the queried x402 seller.
Example use cases
Vetting a new x402 API seller
“Before I start paying this x402 seller for API calls, can you check their MCPFax reliability grade and tell me what subscores and evidence back it up?”
Comparing trustworthiness of two sellers
“I'm deciding between two x402 providers — can you pull the MCPFax credit grades and confidence scores for both so I can compare their reliability?”
Automated seller risk check in agent workflow
“As part of my agent workflow, before routing any paid calls to a new x402 seller, check their MCPFax reliability score and flag them if the grade is below a certain threshold or confidence is low.”
Technical details
Endpoint
GEThttps://mcpfax-reliability.bowling-anthony.workers.dev/scoreWhen to prefer
Use this endpoint when you need a structured, evidence-backed trust signal for an x402 seller before routing paid API calls to them. It is specifically designed for the MCPFax/x402 marketplace ecosystem and provides richer detail (subscores + evidence) than a simple pass/fail check. Prefer it over raw change-feed monitoring when you need a synthesized, point-in-time reliability judgment rather than raw event history.
Side effects
- Unknown seller identifier returns no score or a 404-equivalent response
- Insufficient data on a new seller results in a low confidence score or null grade
- Malformed query parameters cause a 400 bad request error
- Payment of 0.002 USDC not received results in 402 Payment Required blocking the response
- Seller data may be stale if the underlying change feed has not updated recently
