How this service works
Pay-per-call AI services via the 402 Payment Required protocol. No accounts, no API keys — just USDC on Base.
Output
Returns a JSON object with a letter grade (e.g. 'A'), a numeric score (0–100), and individual signals including whether the endpoint is x402-compliant, currently reachable, and its uptime percentage over a recent window.
Example use cases
Pre-integration endpoint vetting
“Before I integrate this new AI microservice at https://api.someprovider.com/v1/summarize, can you run a reputation check on it and tell me its grade and uptime percentage?”
Comparing two agent services
“I'm deciding between two endpoints — can you score https://agentA.io/v1/inference and https://agentB.io/v1/inference and tell me which one has a better reputation grade and whether both are x402-compliant?”
Monitoring a deployed endpoint's trust signal
“Can you check the current reputation score of our deployed endpoint https://myagent.internal/v1/process and flag if the grade drops below B or reachability goes down?”

Choose this endpoint when you need a quick, objective trust signal about a specific API endpoint — especially x402-compatible services — without setting up accounts or API keys. Ideal for pre-integration vetting, agent marketplace trust checks, or runtime health monitoring of microservices in an x402 ecosystem.
Side effects
- Invalid or malformed URL returns a validation error
- Unreachable endpoint may return a low score or error if the target cannot be probed
- Missing endpoint_url field results in a bad request error
- Payment not fulfilled (402) if USDC payment over x402 is not completed
- Timeout if the target endpoint takes too long to probe
