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
A JSON object with three fields: 'ok' (boolean indicating request success), 'allowed' (boolean indicating whether payment settled and access is authorized), and 'summary' (a human-readable string describing the settlement outcome after x402 payment processing).
Example use cases
Example prompt
“Run a metered x402 escrow charge for a GET request so I can verify the payment clears and the endpoint returns allowed:true with a settlement summary.”
Technical details
Endpoint
POSThttps://x402trustlayer.xyz/api/escrow/metered/charge?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to enforce per-call micropayment gating via the x402 protocol for read-style HTTP operations (GET, HEAD, DELETE), specifically within the x402 Trust Layer's semantic escrow infrastructure. Prefer this over generic payment APIs when the downstream service requires x402-protocol compliance and on-chain USDC settlement verification before granting API access.
Side effects
- Payment not settled on-chain — returns allowed:false with summary indicating failed settlement
- Invalid HTTP method supplied (only GET, HEAD, DELETE accepted) — schema validation error
- Missing required 'type' or 'method' fields — 400 bad request
- x402 payment header absent or malformed — payment gateway rejects, 402 returned
- Insufficient USDC balance for $0.01 micropayment — transaction fails, access denied
- Network or chain latency causes settlement timeout — ok:false response
