How this service works
Paid agent-facing brief on Decision procedure for an agent evaluating a real-world-asset (RWA) issuer's x402 payment rail before transacting: verify the issuer surface answers real 402 challenges (not 404/405 weak contracts), confirm network and asset match, check the asset-backing and custody claims that live off-chain on top of the payment rail, validate settlement receipt shape, single go/no-go verdict with kill criteria. Blunt decision procedure, not marketing.
Output
A plain-prose decision procedure (120+ words) with a single go/no-go verdict and explicit kill criteria, covering: verification that the issuer surface responds to real x402 402 challenges (not 404/405), network and asset match confirmation, off-chain asset-backing and custody claim validation steps, and settlement receipt shape validation. Also includes metadata fields: model used, generation source, ISO-8601 timestamp, and service slug.
Example use cases
Vetting tokenized treasury x402 issuer
“I'm about to have my agent buy a tokenized US treasury product from an issuer using x402. Can you run the decision procedure to tell me whether their payment rail is legit — check if they answer real 402 challenges, confirm asset-backing claims, and give me a clear go or no-go before any money moves?”
Screening RWA issuer before automated settlement
“My agent is about to auto-settle with a real-world-asset issuer over x402, but I want a blunt procedure first: do they pass the 402 challenge test, does the network and asset match, and what are the kill criteria that should stop the transaction cold?”
Validating custody and settlement receipts for RWA deal
“Can you generate the decision procedure for evaluating an RWA issuer's x402 rail, specifically focused on validating their off-chain custody claims and the expected shape of the settlement receipt — I need to know exactly what my agent should check before accepting the receipt as valid?”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/decision-procedure-for-an-agent-evaluating-a-reaWhen to prefer
Choose this endpoint when an AI agent needs a structured, opinionated go/no-go checklist specifically for evaluating a real-world-asset issuer's x402 payment rail — not just generic x402 verification. It is purpose-built for the RWA-specific risks (off-chain custody claims, asset-backing, settlement receipt shape) layered on top of the base x402 protocol. Prefer it over generic x402 verification endpoints when the counterparty is a tokenized asset issuer rather than a standard merchant or service provider.
Side effects
- Payment not included or invalid — endpoint returns 402 requiring USDC payment to proceed
- Topic override not recognized — may return generic procedure rather than topic-specific one
- LLM generation failure — generationSource may fall back or result may be empty if upstream model unavailable
- Malformed request — missing required 'input' object with type and method fields returns validation error
- Network timeout — fast latency expected but upstream LLM calls may occasionally exceed threshold
