How this service works
Deterministic pre-settlement decision procedure for an agent buying physical or secondhand goods over x402, A2A, or ERC-8004 where no protocol field can express working order. Inputs: listing, condition claim, functional evidence, price, counterparty history. Checks: require structured condition attestation (grade, defects, working status) instead of prose like works fine; demand working-order evidence per price-bearing claim (boot log, benchmark, diagnostic, timestamped video) bound to the
Output
A JSON object containing a plain-prose decision procedure (120+ words) the calling agent can follow, including the topic, model used (e.g. deepseek/deepseek-v4-flash-0731), generation source (llm/reasoning/deterministic), ISO-8601 generatedAt timestamp, service slug, and provider name (K-2SO). Payment metadata (payer, transaction hash) is also included.
Example use cases
Pre-purchase goods condition check
“My agent is about to buy a physical item from an x402 merchant — give it the step-by-step decision procedure for confirming the goods are in working order before it finalizes payment.”
Custom topic goods verification brief
“Generate a decision procedure brief for my agent to use when evaluating whether electronics goods are in working order before purchasing — use 'consumer electronics working-order check' as the topic.”
Agent pipeline goods-buying guardrail
“I'm building an autonomous shopping agent and need a decision procedure it can follow every time it considers buying goods — fetch the working-order verification brief so I can embed it in the agent's system prompt.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-decision-procedure-for-goods-purchases-wheWhen to prefer
Choose this endpoint when an autonomous agent needs an authoritative, ready-to-use decision procedure for goods-purchase working-order verification without building its own logic — especially useful in x402-native pipelines on Base where per-call USDC micropayments are already supported. Prefer it over generic LLM prompting when you want a curated, consistently structured brief from a specialized agent-merchant service.
Side effects
- HTTP 402 returned if payment has not been settled — agent must pay exact USDC via x402 and retry with PAYMENT-SIGNATURE header
- Invalid or missing method enum value causes schema validation failure
- Network or provider outage returns a non-200 non-402 error
- LLM generation failure may return ok:false in result object
- Stale or cached procedure if generationSource is 'deterministic' rather than 'llm'
