How this service works
Paid agent-facing brief on standalone refund-oracle verification before agent trust: verify a merchant's refund oracle endpoint, signed attestation format, on-rail reversal records, settlement-cycle conformance, signature binding to merchant identity, double-refund guards · Build a decision procedure or schema for: standalone refund-oracle verification before agent trust: verify a merchant's refund oracle endpoint, signed a-0. Blunt decision procedure, not marketing.
Output
A JSON object containing a plain-prose decision procedure (120+ words) covering how to verify a merchant's refund oracle endpoint, signed attestation format, on-rail reversal records, settlement-cycle conformance, merchant identity signature binding, and double-refund guards. Includes a topic field, generation timestamp, model used, and a generationSource enum indicating whether the procedure was generated by LLM, reasoning, or deterministic logic.
Example use cases
Pre-trust refund oracle audit
“Before my agent starts accepting refund claims from this new merchant, give me a step-by-step procedure to verify their refund oracle endpoint and attestation signatures are legitimate.”
Detecting double-refund fraud
“I need a decision procedure my agent can run to detect whether a merchant's refund oracle has double-refund vulnerabilities or lacks proper guards before I route any payments through them.”
Settlement-cycle conformance check
“Can you generate a procedure for checking whether a merchant's on-rail reversal records and settlement-cycle timing actually conform to what their refund oracle claims?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/standalone-refund-oracle-verification-before-age?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous agent needs a structured, actionable checklist or decision procedure for evaluating whether a merchant's refund oracle can be trusted before committing to a payment relationship. Prefer this over generic documentation when you need a blunt, non-marketing procedure tailored to x402 on-rail refund mechanics, signed attestation verification, and double-refund detection.
Side effects
- Payment not received or insufficient — returns unpaid/error state with no procedure
- Oracle endpoint unreachable or malformed URL — procedure may be generic rather than endpoint-specific
- LLM generation failure — may fall back to deterministic procedure or return ok:false
- Invalid query parameters — schema validation error returned
- Topic override not recognized — defaults to core refund-oracle verification topic
