How this service works
Decision procedure and schema for choosing between a user-signed open Checkout Mandate and an agent-signed closed Payment Mandate when an agent reprices a cart after the user leaves. Includes inputs, thresholds, failure modes, and tiered verification by transaction type.
Output
A JSON object containing decision procedure prose for agents ('brief' field), the recommended mandate type based on inputs, applicable thresholds, failure modes, tiered verification rules by transaction type, a generation source indicator (llm, reasoning, or deterministic), and an ISO-8601 timestamp of generation.
Example use cases
Post-checkout cart repricing mandate selection
“My agent just repriced a cart after the user left and I need to know whether to use the open Checkout Mandate or close it out with an agent-signed Payment Mandate — what does the decision procedure say?”
Threshold check for autonomous payment authorization
“What are the thresholds that determine whether my agent can sign a closed Payment Mandate on its own versus requiring the user to have signed an open Checkout Mandate first? Pull the full decision map for me.”
Failure mode review for mandate boundary logic
“Before I ship my checkout agent, I want to understand all the failure modes and tiered verification requirements around the checkout mandate vs payment mandate boundary — can you retrieve that decision procedure?”
Technical details
Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/checkout-mandate-boundary-decision-map?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs authoritative guidance on the mandate authorization boundary during agentic checkout flows — specifically when a cart is repriced after user departure and the agent must decide between an open user-signed Checkout Mandate and a closed agent-signed Payment Mandate. Prefer this over generic payment documentation when you need structured, machine-readable decision logic with explicit thresholds and failure modes tailored to x402-based agentic payment scenarios.
Side effects
- Payment required but not provided — returns 402 with payment instructions
- Invalid or unsupported HTTP method — must be GET, HEAD, or DELETE
- topic override parameter ignored if not a recognized slug
- LLM generation unavailable — may fall back to deterministic source
- Malformed query parameters return validation error
- Service temporarily unavailable — no cached fallback
