How this service works
Trust evidence for any x402 seller origin: is it indexed, does its manifest parse, how many tools does it publish, which chains does it actually advertise, how many settled calls has it been observed receiving on-chain, and would our own Smart Order Router spend buyer money on it. Returns the router's gate field by field, so a refusal is explainable. Never fetches the seller at call time - this is our accumulated crawl and settlement evidence, not a liveness probe.
Output
Returns a trust evidence object for the queried seller origin, including: whether the origin is indexed in x402 discovery, whether the seller manifest parses successfully, the count of tools the seller publishes, the blockchain networks the seller advertises, the number of on-chain settled calls observed, and a boolean or score indicating Smart Order Router eligibility.
Example use cases
Vetting unknown x402 seller before payment
“Before I let my agent pay that x402 endpoint at https://payments.somevendor.io, can you pull its trust evidence — check if it's indexed, how many on-chain settled calls it has, and whether it would pass smart order routing?”
Auditing multi-chain x402 tool publisher
“I want to audit the seller at tools.chainprovider.xyz — tell me which blockchains it actually advertises, how many tools it publishes, and whether its manifest is valid.”
Screening x402 sellers for a marketplace listing
“I'm curating a list of reliable x402 sellers — can you run a trust check on https://agent-api.marketplace-seller.com and tell me its indexing status, settled call count, and Smart Order Router eligibility?”
Technical details
Endpoint
GEThttps://agent402.tools/api/x402/seller-trustWhen to prefer
Use this endpoint when you need to programmatically vet an x402 seller before routing payments to it, curate a trusted set of x402 tools, or diagnose why a seller origin is failing Smart Order Router checks. Prefer this over manual manifest inspection or block explorer lookups when you need a consolidated, multi-signal trust report in a single call.
Side effects
- Unknown or unindexed origin returns low-trust or empty evidence
- Malformed origin URL causes a 400 bad request
- Seller manifest unreachable at crawl time yields parse failure
- On-chain data temporarily unavailable causes partial result
- Rate limiting or payment failure returns 402 or 429
