OpenClaw Firewall · token cost control · security · monitoring
Stop OpenClaw agents from burning your API budget.
OpenClaw Firewall is a gateway between your agents and model providers. Track token usage in real time, set budget limits, and control OpenClaw API costs before they spiral out of control—while also improving cost efficiency, enforcing security protection, and monitoring agent behavior.
Works with OpenClaw and other Claw-based agents. No code changes required.
- OpenClaw API cost control
- Budgets + optimization to reduce waste.
- OpenClaw agent cost monitoring
- Behavior monitoring + request visibility.
Rule: stop runaway loops when tool retries > 10 · tokens > 50k.
OpenClaw Firewall blocks abnormal requests, enforces budgets, monitors suspicious behavior, and protects your API keys automatically.
Why OpenClaw agents can suddenly burn thousands of tokens
OpenClaw agents are powerful, but without guardrails, a single bug or misconfigured tool can create runaway token usage that explodes your API cost.
Infinite loops
Agents repeatedly call themselves or tools with no convergence, generating runaway tokens and unbounded cost.
Tool retries
Aggressive retry strategies on slow or failing tools can spin for minutes, multiplying agent cost.
Heavy reasoning models
Long-context reasoning models amplify every mistake, turning a simple loop into a five‑figure bill.
Real incident
An OpenClaw agent entered a retry loop.
- • 900+ model calls
- • 1.2M tokens consumed
- • Cost burned in minutes
OpenClaw Firewall detects runaway patterns and abnormal behavior automatically—then blocks or throttles requests before costs and risks escalate.
Tip: set per-agent budgets and retry caps to prevent repeat incidents.
What is OpenClaw Firewall
OpenClaw Firewall is a smart gateway between OpenClaw agents and model providers. It adds visibility, budgets, cost optimization, and security protection without changing your agents’ logic.
Track token usage
Per-agent dashboards plus behavior monitoring so you always know where spend goes.
Set budget limits
Hard and soft budgets with alerts and automatic cut-offs—plus optimizations to reduce waste.
Block abnormal requests
Detect runaway patterns, unusual tools, and suspicious prompts before they hit your provider.
Protect your API keys
Keep provider keys behind the firewall so agents never see or leak them—without losing visibility.
Architecture
The firewall sits between your agents and model providers, giving you cost control, security policies, and full visibility.

How to integrate with OpenClaw
Integrating with OpenClaw takes less than 2 minutes.
- 1. Point your agent to the gateway:envOpenClaw Firewall
BASE_URL=https://api.clawfirewall.ai - 2. Create a virtual key (per agent or per environment).
- 3. Set token or cost limits. That’s it—calls now go through the firewall.
Who should use OpenClaw Firewall
- • AI agent developers building with OpenClaw
- • Teams running multiple agents in production
