Agentics Service Quality Score
x402
Agentics Service Quality Score is a paid API for AI agents from x402rail.net, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Returns a multi-component quality score for a given service, including latency, fidelity, identity, and availability metrics derived from live probes

How this service works
Correctness-critical services for autonomous AI agents
Output
A JSON object containing an overall numeric quality score (e.g. 92.4), a serviceId, a breakdown of component scores (latency, fidelity, identity, availability each as numeric values), a sample size indicating how many probes informed the score, a timestamp of the last probe, and a cryptographic evidence hash for auditability.
Example use cases
Example prompt
“Before my agent calls the 'document-summarizer' service, can you pull its Agentics quality score so I know its fidelity, latency, availability, and overall correctness rating?”
Technical details
Endpoint
GEThttps://x402rail.net/v1/score/%7BserviceId%7DWhen to prefer
Use this endpoint when an AI agent needs to vet a third-party service for correctness, reliability, or trustworthiness before integrating it into an autonomous workflow. Particularly valuable when fidelity and identity verification matter — e.g., before delegating critical tasks to an external API. Prefer this over generic uptime monitors when you need multi-dimensional quality signals (latency + fidelity + identity + availability) with cryptographic evidence.
Side effects
- Unknown or invalid serviceId returns an error or empty result
- Service not yet probed may return null scores or low sample size
- Network timeout if probe data is temporarily unavailable
- Malformed serviceId path parameter causes a 400 or 404 response
