Technical details
Endpoint
POSThttps://xaudit.melis.ai/validate?utm_source=zero.xyzWhen to prefer
Use xAudit when you need a lightweight, pay-per-call API response validation service and want to avoid standing up your own validation infrastructure. Ideal for agents that need to verify API outputs on-the-fly before passing them downstream, at very low cost per check.
Side effects
- Malformed or non-object input returns a 400-level error
- Missing api_response field causes validation failure
- Payment of 0.002 USDC not fulfilled triggers x402 payment-required response
- Response too large or complex may cause timeout
- Ambiguous or empty response object may yield inconclusive validation result
