How this service works
Paid agent-facing brief on third-party run-evidence receipt verification for agent execution (hash-chained, Merkle-anchored tool-run proof). Blunt decision procedure, not marketing.
Output
A structured JSON response containing a prose decision-procedure brief ('brief') written for agents, the service slug, an ISO-8601 generation timestamp, the model or generation source used, and boolean flags indicating handler success and payment status. The brief provides actionable, blunt guidance — not marketing copy — on how to verify hash-chained, Merkle-anchored tool-run receipts.
Example use cases
Pre-settlement execution proof vetting
“Before I pay out for this external agent's completed task, walk me through the decision procedure for verifying its hash-chained, Merkle-anchored run-evidence receipt so I can decide if the proof is trustworthy.”
Multi-agent pipeline trust validation
“I'm running a pipeline where one agent delegates work to a third-party tool runner — give me the step-by-step procedure for verifying the tool-run proof receipts before I pass results downstream.”
Audit compliance for agent execution logs
“I need to know the correct decision procedure for validating Merkle-anchored run-evidence receipts from external agent executions so I can document which proofs we accepted during our audit trail review.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/third-party-run-evidence-receipt-verification-fo?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs a concise, actionable decision framework for evaluating third-party run-evidence receipts — specifically hash-chained or Merkle-anchored tool-run proofs — before trusting or settling against external agent execution results. Prefer it over generic documentation when you want a blunt, machine-readable procedure rather than marketing prose. Best suited for agentic workflows where verifying execution integrity from untrusted third-party runners is a prerequisite to payment or downstream action.
Side effects
- Payment not received — returns HTTP 402 requiring USDC micropayment via x402 protocol
- Invalid method — only GET/HEAD/DELETE are accepted; POST/PUT will be rejected
- Schema validation failure if required 'input' object with type and method fields is missing
- LLM or reasoning backend unavailable, causing brief generation to fail
- Topic override parameter malformed, causing unexpected output scope
