Per-Rail Settlement Confirmation Wait-Time Thresholds for x402/MPP Agents
x402
Per-Rail Settlement Confirmation Wait-Time Thresholds for x402/MPP Agents is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status down (last checked 2026-10-18).
Provides a decision table telling x402/MPP agents whether to wait, extend, or declare a settlement dead based on the payment rail, observed confirmation latency, and receipt hash.

How this service works
Decision table for agents that paid an x402/MPP challenge and now must decide when their settlement is actually dead versus merely slow. Per-rail confirmation baselines: Base settles in seconds, XRPL in a few, Solana wants confirmations, Stellar and TRON vary with load. Inputs: rail, observed confirmation latency, receipt hash or null. Outputs: wait verdict per tier (wait, extend, declare-dead), recommended receipt timeout per rail, double-pay risk flag when the agent retries before finality.
Output
Returns a JSON object containing a plain-prose decision procedure (120+ words) advising wait, extend, or declare-dead per tier for the queried rail, a recommended receipt timeout value, a double-pay risk flag for premature retries, an ISO-8601 generatedAt timestamp, and metadata including model, topic, service slug, and generation source (llm, reasoning, or deterministic).
Example use cases
Base settlement stall triage
“My agent paid an x402 invoice on Base 30 seconds ago and hasn't gotten a receipt hash yet — is that normal or should I declare it dead and retry?”
XRPL finality decision for retrying agent
“An XRPL x402 payment has been pending for 12 seconds with no confirmation. What tier does that fall into — wait, extend, or declare-dead — and is there a double-pay risk if I send again?”
Stellar load-variant timeout tuning
“I'm building an MPP agent that pays on Stellar and I need to know the recommended receipt timeout and at what observed latency I should escalate from wait to extend to dead under high network load.”
Technical details
Endpoint
GEThttps://k2so.wrong.systems/api/services/per-rail-settlement-confirmation-wait-time-thres?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an x402 or MPP agent has already submitted a payment and needs a structured, per-rail decision on whether to wait longer, extend its timeout, or declare the settlement dead — especially when double-pay risk on retry is a concern. Prefer it over generic blockchain explorers or static documentation when you need a machine-readable verdict with tiered wait guidance across Base, XRPL, Solana, Stellar, and TRON in a single call.
Side effects
- Missing or invalid rail parameter may result in a generic rather than rail-specific verdict
- Slow or unavailable upstream LLM could delay response or return a degraded generation
- If receipt hash is null the double-pay risk assessment may be less precise
- Payment not received or facilitator credit exhausted returns unpaid/error state
- Network timeout reaching k2so.wrong.systems returns no verdict
