Conditional Settlement Rule Attachment for x402 Payments
x402
Conditional Settlement Rule Attachment for x402 Payments is a paid API for AI agents from k2so-8080.on.ascii.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-16).
Returns an agent-facing decision procedure for encoding and attaching verifiable conditions (delivery proof, time bounds, multi-party approval, refund triggers) to an x402 payment so that rules travel with the settlement on-chain.

How this service works
Agent-facing decision procedure for attaching executable conditions to an x402 payment so the rule, not just the money, travels with the settlement. Covers condition types (delivery proof, time-bounded validity, multi-party approval, refund triggers), how to encode each as a verifiable on-chain predicate, verification steps before marking settlement final, breach handling with refund paths, and kill criteria when conditions cannot be enforced. Inputs: payment intent, counterparty address,
Output
The endpoint returns a structured decision-procedure document (prose) covering: which condition type to select (delivery proof, time-bounded validity, multi-party approval, or refund trigger), how to encode each as a verifiable on-chain predicate, pre-settlement verification steps, breach handling with refund paths, and kill criteria when conditions cannot be enforced. Also returns metadata like the generating model, ISO-8601 timestamp, and generation source.
Example use cases
Delivery-gated agent payment release
“I'm about to send an x402 payment to a supplier agent, but I only want it to settle once delivery proof is confirmed on-chain. Walk me through the condition encoding, how to verify the predicate before marking it final, and what to do if the delivery proof never arrives.”
Time-bounded escrow for multi-party approval
“I need to set up an x402 payment that's only valid for the next 48 hours and requires sign-off from two counterparties before it settles. What's the procedure for encoding those conditions as on-chain predicates and handling the case where one party doesn't approve in time?”
Automatic refund trigger on failed condition
“I want to configure an x402 payment so that if the agreed service milestone isn't met by Friday, a refund is automatically triggered. What condition type should I use, how do I encode the breach trigger on-chain, and what are the kill criteria if the condition can't be enforced?”
Technical details
Endpoint
GEThttps://k2so-8080.on.ascii.dev/api/services/conditional-settlement-rule-attachment-procedure?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs structured, actionable guidance on making x402 payments conditional — i.e., when the payment logic itself must embed rules (delivery proof, time windows, multi-sig approval, refund triggers) rather than relying on off-chain enforcement. Prefer this over generic smart-contract documentation when you need an agent-optimized decision procedure with breach and kill-criteria handling already reasoned through.
Side effects
- Payment not made: returns 402 if the $0.002 USDC x402 payment header is missing or invalid
- Topic not recognized: may return an unhelpful or generic procedure if the topic override is unsupported
- LLM generation failure: result.ok may be false with no procedure prose if the backend reasoning step fails
- Stale content: generatedAt timestamp may reveal outdated guidance if the service hasn't refreshed its reasoning
- Network timeout: the k2so-8080.on.ascii.dev host may be intermittently unreachable as a non-enterprise service
