How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with a list of named health checks (each with URL, status code, reachability flag, and any error), plus aggregate counts for tools, resources, checks performed, and reachable endpoints on the target x402 server.
Example use cases
Verify x402 API before agent use
“Before my agent starts calling https://commerce.example.ai, can you probe it to confirm it's a live x402 server and show me how many tools it exposes? Set a 5-second timeout.”
Health check for x402 marketplace listing
“I'm about to list an API on an x402 marketplace — can you check if https://api.mypayapi.io is reachable and passing x402 discovery checks, with a 10-second timeout?”
Debug unreachable x402 endpoint
“My agent keeps failing when it tries to reach https://api.thirdparty.ai — can you run an x402 server probe on it with a 15-second timeout to see which checks are failing?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/server-probe?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that a specific URL hosts a live, x402-protocol-compliant API before directing an AI agent to call it, or when auditing pay-per-result APIs for health and discovery metadata. It is purpose-built for x402 infrastructure validation rather than general HTTP health checks or uptime monitoring.
Side effects
- Target URL is unreachable or times out — checks array will show reachable:false with an error message
- URL is not an x402-compliant server — discovery check returns non-200 status
- Invalid or missing URL parameter — request rejected with validation error
- Timeout value out of allowed range (1–15 seconds) — request rejected
- Target server returns unexpected response format — partial or empty check results
