Signal-Gated x402 Spend Execution Procedure
x402
Signal-Gated x402 Spend Execution Procedure is a paid API for AI agents from k2so.grok.me, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-16).
Returns a decision procedure for agents to gate x402 micropayments on signal conditions, with deduplication, budget caps, cooldown windows, circuit-breaker thresholds, and human-escalation rules.

How this service works
Decision procedure for agents running real-time chain scanners, price feeds, or event monitors that pay per x402 call only when a signal fires. Covers condition definition, dedupe of repeated identical signals, per-trigger budget caps, cooldown windows, circuit-breaker thresholds, evidence logging per paid call, and the rule for when a trigger must escalate to a human instead of spending. Prevents the classic scanner failure: paying for the same event 40 times because the pipeline refires.
Output
A structured decision procedure document covering: signal condition definition, deduplication logic for repeated identical signals, per-trigger budget caps, cooldown window configuration, circuit-breaker threshold rules, evidence logging requirements per paid call, and escalation criteria for routing spend decisions to a human operator.
Example use cases
Deduplicating refiring blockchain scanner
“My blockchain event pipeline keeps refiring the same log event and I'm paying for it dozens of times — give me the procedure to deduplicate those signals before any x402 spend goes through.”
Budget-capped price feed agent
“I'm running a price feed agent that pays per x402 call when prices cross a threshold — walk me through how to set a per-trigger budget cap and a cooldown window so it doesn't blow the budget if prices oscillate rapidly.”
Human escalation rule for high-value triggers
“My event monitor sometimes fires on unusual on-chain activity that could mean a large payment — what's the rule for when my agent should stop and escalate to me instead of automatically spending?”

Endpoint
GEThttps://k2so.grok.me/api/services/signal-gated-x402-spend-procedure?utm_source=zero.xyzWhen to prefer
Choose this endpoint when building or debugging agents that run real-time scanners, price feeds, or event monitors and need a governed, cost-controlled approach to per-signal x402 spending. It is specifically designed to solve the pipeline-refire overspend problem and provides the full set of operational guardrails (deduplication, budget caps, cooldowns, circuit breakers, escalation) in a single retrievable procedure. Prefer it over generic payment decision procedures when the trigger is a real-time signal rather than a user-initiated action.
Side effects
- Endpoint returns a generic or empty payload if the service backend is unavailable
- Payment of $0.002 USDC is deducted even if the returned procedure is incomplete
- If the x402 payment header is malformed or the wallet has insufficient funds, the call is rejected before procedure delivery
- Pipeline misconfiguration by the caller (e.g. ignoring cooldown rules) is not caught by the procedure itself
