How this service works
Paid agent-facing brief on agent execution attestation and deliverable proof verification: proving an agent actually performed the work after payment, binding deliverables to attestations, escrow release readiness-0. Blunt decision procedure, not marketing.
Output
A JSON object containing a plain-prose decision procedure brief (120+ words) describing how an agent should handle execution attestation and deliverable proof verification, along with metadata including the generating LLM model name, ISO-8601 generation timestamp, generation source enum (llm/reasoning/deterministic), topic string, and service slug. The 'brief' and 'procedure' fields contain the actionable guidance text.
Example use cases
Verifying agent task completion before payout
“My payment agent just finished a data-scraping job — what's the correct procedure for attesting that it actually completed the deliverable before I release the USDC payment?”
Building an x402 service with attestation support
“I'm building an x402 agent service and need to understand the decision procedure for proving that my agent executed and delivered the output — can you walk me through what attestation should look like?”
Auditing autonomous agent execution logs
“We're auditing our fleet of autonomous agents and need a decision procedure for verifying that execution attestations in our logs are valid proof of deliverable completion — what's the correct framework?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/agent-execution-attestation-and-deliverable-proo?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous agent or agent-builder needs a structured, LLM-generated decision procedure specifically for execution attestation and deliverable proof in the x402 micropayment context. Prefer this over generic AI chat when you need a consistent, paid, machine-readable brief with provenance metadata (model, timestamp, source) that can be logged or re-used across agent workflows. Best suited for agents that need governance documentation or runtime decision support for verifying task completion.
Side effects
- HTTP 402 returned if payment not settled — must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Missing or malformed required 'input' object returns validation error
- Invalid method enum value (not GET/HEAD/DELETE) returns schema error
- LLM generation failure may result in ok:false with empty brief
- Topic override string may be ignored if it conflicts with the hardcoded service context
