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 a boolean ok/allowed status, an ordered array of steps (each with path, price in USDC, and purpose), a human-readable plan summary, total estimated USDC cost, whether the plan is within the specified budget, the recommended first step URL, and the suite base URL.

Example use cases

Example prompt

“Can you compile a GET-based x402 trust layer payment intent plan and tell me which API steps to run, in what order, and whether the total estimated cost fits within a $1 USDC budget?”

Endpoint

When to prefer

Use this endpoint when you need to pre-plan and cost-estimate a sequence of x402 trust layer API calls before executing them — especially when operating under a USDC budget constraint and needing an ordered execution roadmap with guard, router, and receipt-auditor steps. Prefer this over ad-hoc API calls when orchestration, budget compliance, and step sequencing matter.

Side effects

Invalid or missing 'type' field (must be 'http') returns validation error
Unsupported HTTP method (only GET, HEAD, DELETE allowed) returns enum violation error
Budget exceeded results in withinBudget: false with plan still returned
Service unavailable or upstream routing failure returns non-ok status
Malformed input object causes schema rejection
