How this service works
Deterministic gate for an agent that paid for goods via machine payment and must delegate IRL pickup to a courier or third party. Ordered checks: endorsement chain from the paying wallet, signature validity with nonce, scope binding to specific items and location, endorsement expiry inside the receipt freshness window, collector identity binding, one-time consumption so payer and collector cannot both redeem, and collector default risk holding settlement without delivery confirmation. Outputs
Output
A JSON object containing a plain-prose decision procedure brief (120+ words) tailored to delegated pickup endorsement verification, including the model used to generate it, the topic, a generation timestamp, the generation source (llm/reasoning/deterministic), and payment confirmation metadata.
Example use cases
Autonomous logistics agent pickup validation
“My agent is about to accept a delegated pickup request from a third-party courier — can you give me the full decision procedure it should follow to verify the endorsement is legitimate before releasing the goods?”
Agent compliance review for endorsement delegation
“I'm building an autonomous agent that handles delegated pickups on behalf of merchants; walk me through the verification procedure it should run to stay compliant when checking endorsements.”
Custom topic endorsement verification brief
“Generate the decision procedure for an agent verifying a delegated pickup endorsement specifically in the context of cross-border parcel handoffs — use that as the topic override.”

Endpoint
GEThttps://k2so.wrong.systems/api/services/delegated-pickup-endorsement-verification-proced?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a structured, prose-format decision procedure specifically for verifying delegated pickup endorsements and you want a ready-to-use, LLM-generated brief rather than writing the logic yourself. It is ideal for autonomous agent pipelines that require on-demand compliance guidance at micropayment scale ($0.002 USDC), especially when the agent operates on Base with USDC and supports the x402 payment protocol.
Side effects
- HTTP 402 returned if payment has not been settled — agent must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Malformed or missing payment signature results in rejection
- Invalid queryParam values (e.g. unsupported meta value) may cause schema validation errors
- Service may return ok:false in the result object if the handler fails internally
- Network or upstream LLM errors may cause delayed or empty brief responses
