How this service works
Choose Blockchain Money Map for human-readable public blockchain reports or x402-paid agent API services.
Output
A JSON trust assessment comparing the submitted service facts against reference facts, flagging any inconsistencies in service name, buyer promise, price, output description, or metadata, and producing an overall trust/verification verdict for the buyer agent to act on.
Example use cases
Pre-payment fraud check for agent marketplace
“I'm about to have my agent pay for a service called 'WalletRiskScore' that promises 'a 0-100 risk score for any wallet address' at $0.02 per call — can you verify those claims against the reference facts I provide and flag any discrepancies before the payment goes through?”
Validating agent card claims before onboarding
“I want to onboard a new data service into my agent fleet — it's called 'NFT Price Oracle' and its agent card says it delivers 'floor price in USD for any NFT collection' with no listed limitations. Run a trust passport plus check against the reference facts I have and tell me if the seller's claims hold up.”
Auditing x402 seller consistency for compliance
“For compliance purposes, check whether the seller's stated facts for 'TxStatusChecker' — price $0.01, output described as 'transaction confirmation status and block number' — are consistent with the reference facts from our approved vendor list, and give me the verification result.”
Technical details
Endpoint
POSThttps://api.blockchainmoneymap.com/api/x402/x402-agent-buyer-trust-passport-plusWhen to prefer
Choose this endpoint when an AI agent needs to programmatically verify the trustworthiness of another agent service's advertised claims before committing to an x402 micropayment — especially in automated agent-to-agent commerce pipelines where human oversight is absent. Prefer this over manual review when you have structured reference facts to compare against and need a machine-readable trust verdict at decision time.
