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 three fields: 'ok' (boolean indicating the call succeeded), 'allowed' (boolean indicating whether the request is permitted under x402 guard rules), and 'summary' (a human-readable explanation of the decision), e.g. {"ok": true, "allowed": true, "summary": "Paid response after x402 settlement"}.

Example use cases

Example prompt

“Can you run a GET request through the x402 Trust Layer guard sandbox to check if it's allowed — the type is 'http' and there are no extra query params?”

Technical details

Endpoint

POSThttps://x402trustlayer.xyz/api/guard/payload-sandbox?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to sandbox or pre-validate whether a specific HTTP request (GET, HEAD, or DELETE) is permitted under x402 guard policy before executing it. Prefer this over live guard endpoints when doing dry-run compliance checks or testing mandate-governed access rules without triggering real state changes.

Side effects

Invalid or unsupported HTTP method (only GET, HEAD, DELETE accepted) — likely returns a validation error or 422
Missing required 'input' field or 'type'/'method' subfields — returns schema validation error
Unsettled or missing x402 payment — returns 402 Payment Required
Internal service error — returns 500 with error detail
Request type value other than 'http' const — rejected by schema validation
