How this service works
68 paid x402 trust infrastructure APIs: guard, semantic escrow, mandate diff, certified seller network, KYM, mandates, compliance, disputes, and orchestration.
Output
Returns a JSON object with 'ok' (boolean indicating call success), 'allowed' (boolean indicating whether the request is authorized post-settlement), and 'summary' (string describing the outcome after x402 payment settlement).
Example use cases
Escrow API call authorization check
“I have a JSON POST request that needs to go through x402 semantic escrow binding before it's authorized — can you replay it through the x402 trust layer and tell me if it's allowed after payment settlement and what the outcome summary says?”
Mandate compliance replay validation
“Before I let this PATCH request go through, I want to verify it's compliant with our x402 mandates — replay it through the x402 trust infrastructure and give me a yes or no on whether it's authorized, plus a summary of what happened after settlement.”
Guard enforcement for PUT request
“I need to run a PUT request with a form-data body through the x402 guard and make sure it passes trust layer authorization after settlement — can you bind it via x402 protocol replay and report back whether it's allowed and what the result summary looks like?”
