How this service works
Decision procedure for an agent that paid an x402 endpoint and received a settlement receipt it cannot verify on-chain. Covers: opacity tier scoring (verifiable tx hash with explorer logs vs private-ledger claim vs screenshot or missing hash), accept / request-corrective-proof / escalate / blacklist verdicts per tier, what counts as a corrective proof (explorer URL, event-log match, signed receipt from facilitator), audit-trail requirements before escalating, recourse thresholds by payment size
Output
A JSON object containing a plain-prose decision procedure brief (120+ words) tailored for AI agents, along with the topic label, service slug, generating model name, generation source (llm/reasoning/deterministic), and ISO-8601 timestamp. The 'brief' and 'procedure' fields contain the actionable guidance text the agent can directly use.
Example use cases
Handling unverifiable x402 payment receipts
“My autonomous merchant agent got back a payment signature it can't parse — generate a decision procedure brief so it knows whether to accept, reject, or escalate this opaque settlement proof.”
Building agent policy for settlement edge cases
“I'm designing a payment handling policy for my x402 agent on Base and need a clear prose decision procedure for situations where a settlement proof is ambiguous or opaque — can you produce that brief?”
Auditing agent behavior on failed verifications
“Walk me through the decision logic my AI agent should follow when it encounters a USDC settlement proof it cannot independently verify on Base, so I can audit and document its behavior correctly.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-facing-decision-procedure-for-opaque-or-un?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs on-demand, LLM-generated procedural guidance specifically for handling opaque or unverifiable x402 USDC settlement proofs on Base. Prefer it over static documentation when you need reasoning-fresh advice that reflects the nuances of your specific topic override, or when building autonomous agent decision trees that must handle payment edge cases dynamically. Not suitable for real-time transaction verification or on-chain data lookups.
Side effects
- Payment not settled — returns HTTP 402 with PAYMENT-REQUIRED header requiring exact USDC payment before retry
- Invalid HTTP method (POST/PUT/PATCH) — schema only allows GET/HEAD/DELETE
- Malformed query parameters — non-enum value for meta field causes validation error
- Service temporarily unavailable — upstream LLM or reasoning engine failure returns error with ok:false
- Topic override too vague or unsupported — may return a generic rather than tailored procedure
