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 verdict field (e.g. 'MATCH' or 'MISMATCH'), a payer type, and a product identifier. If MISMATCH, the live 402 challenge is demanding a different amount than the listed price, signaling the agent should not pay without investigation.
Example use cases
Pre-payment price sanity check
“I'm about to pay for an x402 API call — can you verify that https://signals.messari.io/v1/report actually charges what it claims to charge before I send any USDC?”
Detecting bait-and-switch on x402 listing
“I saw an x402 listing priced at $0.05 USDC but I want to make sure the live endpoint at https://data.example.io/prices isn't actually demanding more than advertised — can you check for a mismatch?”
Agent workflow guard before micropayment
“As part of my automation, before paying any x402 resource, run a listing check on https://pathmint.edge.report/v1/listing-check to confirm the price the API is actually asking for matches what was listed, and only proceed if they match.”
Technical details
Endpoint
GEThttps://pathmint.edge.report/v1/listing-check?utm_source=zero.xyzWhen to prefer
Use this endpoint whenever an AI agent is about to execute an x402 micropayment and wants to confirm the live price challenge matches the advertised listing price. This is especially valuable in automated workflows where an agent might process many x402 calls and needs a cheap ($0.02) guard against price manipulation or stale listings before committing funds.
Side effects
- URL not reachable — resource may be a ghost listing or timed out
- URL does not serve an x402 402 response — endpoint is not an x402 resource
- Verdict returns MISMATCH — live price differs from listing, do not pay
- Missing required 'url' query parameter — request rejected
- Network timeout reaching the target resource
