Agentic buyer workflows
Agents need to discover, compare, pay, verify, and remember what they bought.
Trust402 can sit before payment as a route scorer and after payment as a receipt/proof planner.
Base/x402 agent commerce is moving toward wallet-enabled buyer agents, marketplace discovery, approval-gated purchases, bundled paid intelligence, and verification-native receipts.
Agents need to discover, compare, pay, verify, and remember what they bought.
Trust402 can sit before payment as a route scorer and after payment as a receipt/proof planner.
Visible paid services cluster around concise research, market briefs, scanners, and decision reports.
Trust402 should package endpoint diligence as a paid decision report, not only as raw endpoint checks.
Agents need endpoints that remain discoverable, recently settled, and richly described enough for semantic search.
Trust402 can publish route-level evidence, score metadata quality, and keep Radar/receipt artifacts crawlable.
Human-approved Base MCP payments favor larger, higher-confidence purchases over noisy microcalls.
Trust402 should present one clear quote, maxPayment guidance, and receipt expectations before an agent asks for approval.
Payment alone does not prove that the right service responded, that the result was delivered, or that no replay/binding mistake happened.
Trust402 should keep emphasizing challenge binding, price checks, public discovery, result hashing, and Proof402-ready evidence.
Agents need to avoid leaking private task details through payment descriptions, URLs, headers, and facilitator-visible metadata.
Trust402 should continue stripping payment headers from unpaid probes and guide sellers toward minimal public metadata.
Sellers need to prove that payment metadata, price consistency, request binding assumptions, and replay controls are safe before agents trust them.
Trust402 should package seller readiness and diligence as x402 security posture checks, not just marketing readiness.
| Step | Decision | Trust402 route |
|---|---|---|
| discover | Read /.well-known/x402, OpenAPI, resource catalogs, and marketplace listings before considering payment. | /api/resources |
| screen | Check schema, price, x402 challenge, network, receipt readiness, and public seller metadata. | /api/trust/score-resource |
| compare | Rank 2-10 candidate resources by goal fit, risk, price, discovery completeness, and proof readiness. | /api/trust/compare-resources |
| approve | Ask the user or policy engine for a bounded maxPayment only after the route and quote are clear. | /api/procurement/quote |
| verify | Hash the purchased result, preserve public-safe evidence, and notarize only approved hashes when proof delegation is enabled. | /api/receipts/hash-result |
| monitor | Recheck payment-flow drift, challenge changes, and seller metadata before repeat purchases. | /api/monitor/snapshot |
