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 structured prose brief and decision procedure (and optionally a procedure schema) covering: settlement proof verification, discovery presence signals, price fairness relative to alternatives, dispute and delivery history review, and explicit kill criteria for anonymous or unverifiable payees. Response includes ok/paid status, ISO-8601 timestamp, generation source, and the provider slug.
Example use cases
Pre-approval gate for new x402 vendor
“Before my agent pays this new x402 merchant I've never seen before, give me a deterministic checklist — settlement proof, dispute history, price fairness — and tell me exactly when to reject outright.”
Kill-criteria schema for anonymous payees
“I need a strict vetting schema my agent can run against any anonymous or unverifiable x402 payee to decide whether to block payment entirely — what are the hard no-go signals?”
Merchant trust scoring before bulk payments
“My agent is about to authorize recurring x402 payments to a set of new merchants — walk me through the deterministic pre-grant procedure so it can flag risky ones before any funds move.”

Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/merchant-vetting-authority-deterministic-pre-graWhen to prefer
Use this endpoint when an AI agent needs a structured, opinionated decision procedure — not generic advice — for vetting a new x402 merchant before authorizing payment. Prefer this over general-purpose LLM prompts when you need a consistent, repeatable schema with explicit kill criteria and settlement-proof requirements baked in. Best suited for agentic payment pipelines that require a deterministic pre-grant gate rather than a fuzzy risk score.
Side effects
- Payment not received — returns 402 requiring x402 micropayment before content is delivered
- Handler failure — ok: false with no brief returned
- Invalid query parameter values — schema validation error
- Service temporarily unavailable on the ascii.dev host
- Empty or malformed topic override yields generic rather than targeted procedure
