Vibes-Coded Agent State Guard
x402
Vibes-Coded Agent State Guard is a paid API for AI agents from vibes-coded.com, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).
Validates AI agent state before executing an action by checking retry budget, memory coherence, and pending actions, returning a risk score and proceed/halt recommendation.

How this service works
Pay-per-call JSON for AI agents: skill search, listing optimization, install plans, productization, and artifact risk scoring. HTTP 402 → USDC. Full skill marketplace on-site.
Output
Returns a JSON object with a boolean ok field, a risk level string (e.g. 'low'), a checks object containing retry_budget status, memory_coherent boolean, and no_pending_action boolean, a state_ok boolean, and a human-readable recommendation string such as 'proceed' or 'halt'.
Example use cases
Pre-action safety gate for agents
“I'm about to execute a payment action in my agent loop — can you run a state guard check first to confirm my retry budget hasn't been exhausted and there are no conflicting pending actions before I proceed?”
Memory coherence check before tool use
“My agent is about to call an external tool but I want to make sure its memory is still coherent and there's no stale state that could cause problems — run an agent state guard check and tell me if the risk level is low enough to continue.”
Loop detection and halt recommendation
“My agent has been retrying a task several times and I'm worried it's stuck in a loop — check its current state, look at the retry budget and any pending actions, and tell me whether I should let it keep going or halt it.”
Technical details
Endpoint
POSThttps://vibes-coded.com/api/v1/outcomes/agent-state-guardWhen to prefer
Use this endpoint as a pre-flight check before any high-stakes agent action — especially before payments, external API calls, or irreversible operations. Prefer it over custom state-checking logic when you need a structured risk score with memory coherence and retry budget analysis in a single call. Particularly useful in long-running agentic loops where state drift and retry exhaustion are real risks.
Side effects
- HTTP 402 if USDC payment not provided or insufficient — agent must implement x402 payment flow before retrying
- Malformed or missing agent state payload returns validation error
- Ambiguous or incomplete state data may result in conservative 'halt' recommendation even when agent is healthy
- Network timeout if agent state payload is very large
