How this service works
Evaluates refund cases and decides whether a payment should be refunded.
Output
Returns an arbitration decision or outcome indicating whether a refund is warranted, based on the submitted quality signals such as whether the response was empty, generic, the endpoint was reachable, and the verification score.
Example use cases
Example prompt
“Evaluate this refund arbitration case: the endpoint was reachable, but the response was empty and generic, with a verification score of 0.2 — what's the refund decision?”
Technical details
Endpoint
POSThttps://x402-agent-suite-production.up.railway.app/api/refund-arbiter/evaluateWhen to prefer
Use this endpoint when you need an automated, paid arbitration decision on whether a refund is warranted for a prior API call, specifically when you have quality signals such as response emptiness, response genericity, reachability status, and a numeric verification score. Best suited for x402-protocol payment flows where refund disputes need programmatic resolution.
Side effects
- Missing required fields returns validation error
- Invalid verificationScore type (non-number) causes processing failure
- Endpoint unreachable returns timeout or connection error
- Payment failure via x402 protocol blocks access with 402 status
- Ambiguous boolean inputs may produce uncertain arbitration outcome
