Seller Trust

by Check an x402 seller's trust in Security & trust

x402 APIPassing, checked 3 h ago

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.
