How this service works
Deterministic decision procedure for an agent choosing between x402 facilitators at high transaction volume. Ordered checks: settle-on-rail verification via live 402 challenge, cost-per-call vs task value, published scale evidence scoring (unverifiable volume claims are unproven), payment payload version compatibility (a facilitator that rejects your wallet's payload version fails immediately regardless of claimed scale), and failure-mode handling for settlement timeout, retry storms, and
Output
A JSON response containing a plain-prose decision procedure brief (120+ words) tailored to evaluating an x402 facilitator's reliability and scale, including the topic, service slug, generation timestamp, model used, and generation source (llm, reasoning, or deterministic).
Example use cases
Choosing a facilitator for production agent
“My autonomous agent is about to go live and needs to pick an x402 facilitator — can you run the reliability and scale vetting procedure so I know which one is safe to depend on for high-volume micropayments?”
Evaluating a new facilitator before onboarding
“I've been offered a new x402 facilitator to route my agent's payments through — can you generate a vetting brief on its reliability and whether it can handle the scale I need?”
Quarterly review of existing facilitator
“I want to reassess the x402 facilitator my agent fleet is currently using — run the per-facilitator reliability and scale decision procedure so I can decide whether to stick with them or switch.”

Endpoint
GEThttps://k2so.wrong.systems/api/services/per-facilitator-x402-reliability-and-scale-vetti?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your autonomous agent needs a structured, agent-readable decision framework for evaluating whether a specific x402 facilitator meets reliability and throughput requirements — especially before committing to a facilitator for production workloads or high-frequency micropayment flows. Prefer over generic web search or manual research when you need a concise, actionable prose brief optimized for agent consumption.
Side effects
- HTTP 402 returned if payment not yet settled — must pay exact USDC amount and retry with PAYMENT-SIGNATURE header
- Invalid or missing 'input' object returns validation error
- Facilitator slug not recognized may result in generic or empty brief
- LLM generation failure may fall back to deterministic source
- Network timeout if agent retries too quickly after payment settlement
