The Real-Time Circuit Breaker for Autonomous AI Agents.

A single-line cloud API gateway proxy that detects recursive infinite loops, token context explosions, and runaway sessions before they drain your production OpenAI or Anthropic budgets. Installs in 60 seconds with <15ms overhead.

Why Traditional AI Infra Let Your Production Budgets Bleed

Passive logging tools show you a graph after the fire. AgentCircuit cuts the power in real-time.

Passive Logs & Tracing

Platforms like LangSmith or Datadog process logs asynchronously. They will happily charge you money to process the very logs generated by your runaway infinite loop, alerting you hours after the damage is done.

Hard Account Credit Caps

Shuts down your entire API key or provider account when a budget threshold is met. This kills healthy, revenue-generating customer sessions alongside the buggy ones, causing catastrophic application downtime.

AgentCircuit Stateful Proxy

Evaluates temporal token density and semantic trajectory curves at the network level. Actively blocks individual recursive loop sessions within 5 iterations while keeping the rest of your app completely healthy.

How It Works

Three steps from unprotected traffic to session-level circuit breakers.

  1. 01

    Route Traffic Through Our Proxy

    Change your model's base URL environment variable to point to our gateway. Zero heavy SDKs, packages, or code dependencies to install.

  2. 02

    Semantic Trajectory Tracking

    Our lightweight proxy evaluates prompt-to-response repetition density and recursive error patterns across streaming data in real-time.

  3. 03

    Trip the Circuit Breaker

    If a runaway agent loop is detected, the gateway drops a hard HTTP 429 block on that specific session, preserves your budget, and triggers emergency alerts via Slack or PagerDuty.
