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 success), 'allowed' (boolean access decision), and 'summary' (string explanation of the proof result) after x402 USDC payment settlement.

Example use cases

Verify agent action without data exposure

“I need to prove that this agent's API request is authorized under our mandate without revealing the underlying payload — can you run a zero-knowledge proof on it and tell me if the action is allowed and why?”

Compliance check for sensitive transaction

“Before we settle this transaction, run a ZK compliance check on the POST body through the x402 Trust Layer and confirm whether it passes our mandate rules — give me the decision and a plain-language explanation.”

Attest seller credentials privately

“We need to verify this seller is part of our certified network without exposing their private data — use the x402 Trust Layer to generate a zero-knowledge attestation and let me know if they're approved and the reason.”
