# AI Circuit Breaker

> The Zero-Overhead Reverse Proxy & Infinite-Loop Firewall for Autonomous AI Agents.

AI Circuit Breaker intercepts chat completion calls to upstream providers (OpenAI, Anthropic), detects recursive agent error loops using a sliding-window SHA-256 hash deque, and kills runaway streams before budget exhaustion.

## Quickstart Drop-in
- Base URL: https://circuit-breaker-api.onrender.com/v1
- Upstream Compatibility: 100% OpenAI /v1/chat/completions compatible.
- Latency Overhead: <35ms.
- Streaming: Unbuffered Server-Sent Events (SSE).

## Integration Example (Python)
```python
from openai import OpenAI

client = OpenAI(
    base_url="https://circuit-breaker-api.onrender.com/v1",
    api_key="cb_live_your_proxy_key"
)

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "Execute agent task..."}],
    stream=True
)
