How this service works

24 paid x402 infrastructure APIs for AI agent fleets: buy advisor, audition coach, guard, proxy, MPP, attestations, and pipeline orchestration.

Output

Returns a JSON object with three fields: 'ok' (boolean indicating success), 'allowed' (boolean indicating whether access is permitted), and 'summary' (a human-readable string describing the probe outcome after x402 payment settlement).

Example use cases

Validate third-party API availability

“Before I send requests through this third-party service provider, can you quickly probe their API endpoint to make sure it's actually reachable and we're allowed to access it? I need to know the quality status before routing my fleet traffic there.”

Monitor agent fleet gateway health

“I want you to periodically check if our internal gateway endpoint is still responding properly and accessible. Can you run a health probe on it and let me know if there are any permission or reachability issues that might block our agents?”

Verify paid service endpoint access

“We're about to integrate with a new x402-enabled microservice, but I need to confirm it's genuinely available and that our payment settlement allows us through. Can you probe the endpoint and tell me if we actually have access permissions?”

When to prefer

Use this endpoint when you need a paid, authenticated quality check on an HTTP endpoint (GET, HEAD, or DELETE) as part of an x402-enabled agent fleet infrastructure. Prefer this over generic uptime monitors when you need the x402 payment layer and structured ok/allowed/summary response for downstream agent decision-making.

Side effects

Payment not settled — returns 402 with x402 payment required header
Invalid HTTP method provided (only GET, HEAD, DELETE accepted) — validation error
Target endpoint unreachable — ok: false, allowed: false with summary explaining failure
Missing required 'input' field — schema validation error
Network timeout on probe — ok: false with timeout summary
