Technical details
Endpoint
POSThttps://x402trustlayer.xyz/api/mcp/tools/call?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a cryptographically-backed trust decision (guard, compliance, escrow, mandate verification) that is settled on-chain via x402 micropayment. Prefer this over generic API gateways when the workflow requires certified seller verification, semantic escrow release, or KYM (know your mandate) compliance as part of an agent-to-agent or agent-to-API interaction.
Side effects
- Payment not settled — x402 micropayment failed, returns 402 Payment Required
- Method not allowed — only GET, HEAD, DELETE are accepted; POST/PUT return validation error
- Missing required 'type' or 'method' fields in input object — returns schema validation error
- Chain verification failure — mandate status unresolvable on supported chains
- Escrow settlement timeout — quality escrow not confirmed in time
