How this service works
Decision procedure for agents with long-running x402 payment loops to detect endpoint drift, decide when to re-probe a previously vetted merchant, and choose between re-vet, retire, or spend-cap actions with drift evidence logging.
Output
A JSON object containing a plain-prose decision procedure (120+ words) describing how an agent should evaluate merchant drift and decide on re-vetting, along with metadata: the LLM model used, the topic string, service slug, generation source (llm/reasoning/deterministic), and ISO-8601 timestamp. Payment confirmation fields (paid, payer, transaction) are also included.
Example use cases
Autonomous merchant re-audit trigger
“My agent has been paying the same x402 merchant for two weeks and its service description seems to have changed — give me a decision procedure for re-vetting it to decide whether to keep using it or flag it for review.”
Agent governance policy for merchant drift
“I'm building an agent fleet that pays x402 merchants automatically — generate a decision procedure my agents can follow to detect merchant drift and decide when to pull the plug on a merchant relationship.”
Compliance review of on-chain merchant behavior
“One of the merchants in our autonomous payment system started returning different data than when we first approved it — walk me through the steps an agent should take to re-vet that merchant and determine if it's still trustworthy.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/merchant-drift-revet-decision-procedure?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous agent needs a structured, LLM-generated prose decision procedure specifically for merchant re-vetting or drift detection in an x402 micropayment context. It is purpose-built for agent-to-agent governance workflows where the consumer agent needs actionable decision logic rather than raw data. Prefer it over general-purpose LLMs when you want a pre-scoped, consistently formatted governance brief at low cost ($0.002 USDC) without managing prompt engineering yourself. Use the topic override parameter to tailor the procedure to a specific merchant scenario.
Side effects
- HTTP 402 returned if payment has not been settled — agent must pay exact USDC via x402 protocol then retry with PAYMENT-SIGNATURE header
- Invalid or malformed query parameters may cause a 400-level error
- LLM generation failure may result in ok:false in the result object
- Network or provider downtime on wrong.systems infrastructure
- If meta=1 is set, returns free metadata JSON instead of the paid decision procedure
