How this service works
Paid agent-facing brief on merchant vetting authority: deterministic pre-grant vetting procedure for agents deciding whether to preapprove a new x402 merchant (settlement proof, discovery presence, price fairness vs alternatives, dispute and delivery history, kill criteria for anonymous or unverifiable payees) · Build a decision procedure or schema for: merchant vetting authority: deterministic pre-grant vetting procedure f. Blunt decision procedure, not marketing.
Output
A JSON object containing a plain-prose decision procedure brief (120+ words) describing the steps an agent should follow to vet a merchant before granting access, along with metadata including the topic, model used, generation source (deterministic), ISO-8601 timestamp, service slug, and payment confirmation fields.
Example use cases
Pre-screening a new x402 service provider
“Before I let my agent start paying this new x402 merchant on Base, I want to run the deterministic pre-grant vetting procedure on it — can you pull that decision brief so I know what checks to apply?”
Governance policy for agent wallet allowlisting
“I'm building an agent wallet that needs to vet merchants before adding them to its allowlist — fetch the deterministic merchant vetting authority procedure so I can encode those rules into my governance flow.”
Compliance audit of merchant onboarding process
“I need to audit how my autonomous agent system currently onboards x402 merchants — get me the pre-grant vetting decision procedure brief so I can compare it against what we're actually doing.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/merchant-vetting-authority-deterministic-pre-graWhen to prefer
Choose this endpoint when an autonomous agent or developer needs a structured, deterministic (not LLM-stochastic) pre-grant vetting procedure for x402 merchants — particularly in governance flows, allowlist management, or compliance audits where reproducible decision logic is required. Prefer over LLM-generated equivalents when consistency and auditability matter. Best suited for agent-to-agent payment networks operating on Base with USDC micropayments.
Side effects
- HTTP 402 returned if payment not yet settled — agent must pay exact USDC amount then retry with PAYMENT-SIGNATURE header
- Invalid or missing payment signature results in continued 402 rejection
- Network or provider downtime may return 5xx errors
- Malformed query parameters (e.g. invalid meta value) may return 400
- Topic override not recognized may still return a generic procedure brief
