How this service works
Proven Path Exchange — compile sealed procedures when the savings vs the fee are checkable. Primary: verify-before-pay clearance of an x402 payTo.
Output
Returns a JSON object with a 'live' boolean (true if the endpoint is reachable and active), a 'dead' boolean (true if unreachable or a ghost), and a 'product' string identifying the service (e.g. 'pathmint-ping').
Example use cases
Pre-payment liveness check
“I'm about to pay for access to this x402-gated endpoint at https://data.someprovider.io/v1/feed — can you ping it first to make sure it's actually live and not dead before I send any USDC?”
Validating a received payTo address
“I got a 402 response with payTo address 0xAbC123... from https://api.thirdparty.com/premium/results — can you verify that URL and payTo combination is a real, live x402 endpoint before I proceed?”
Screening x402 URLs in bulk workflow
“Before my agent pipeline pays for any of these x402 endpoints, ping https://content.example.com/v1/article to check whether it's a ghost or a live resource so we don't waste money on dead links.”
Technical details
Endpoint
GEThttps://pathmint.edge.report/v1/pingWhen to prefer
Choose this endpoint when you need a lightweight, cheap ($0.01 USDC) pre-flight check before committing a larger micropayment to an x402-gated resource. Ideal for agent pipelines that must screen multiple x402 URLs for liveness before executing payment flows, or any scenario where a 'ghost' (dead) x402 endpoint would waste funds or cause downstream failures.
Side effects
- URL is unreachable — returns {live: false, dead: true}
- Invalid or missing 'url' query parameter — likely a 4xx validation error
- Target URL is not an x402 resource — may return dead=true or unexpected status
- Network timeout reaching the target resource — may result in error or dead=true response
- Rate limiting or payment failure for the $0.01 USDC call itself
