How this service works
Machine-payable agent API with free discovery and preview tools, plus x402-paid execution endpoints for structured agent results.
Output
A JSON object containing a 'risk_level' field (e.g. 'low', 'medium', 'high') and an 'explanation' string describing which patterns were detected and why the command is or isn't considered dangerous.
Example use cases
Pre-execution safety gate for agent
“Before my automation agent runs this shell command it generated — 'find / -name "*.env" -exec cat {} \;' — can you check what risk level it gets and whether it's safe to execute?”
CI/CD pipeline command vetting
“We're about to run this command in our deployment pipeline: 'chmod 777 /etc/sudoers && echo "ALL ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers' — can you assess the risk level for me before we proceed?”
User-submitted script screening
“A user submitted this shell snippet to run on our server: 'dd if=/dev/zero of=/dev/sda bs=1M' — what's the risk level and should I block it?”
Technical details
Endpoint
GEThttps://api.kgninja.dev/shell-risk-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, fast, per-call risk classification of individual shell commands before execution — especially in agentic pipelines where an AI may be generating or relaying shell commands and you want a safety gate. Prefer this over manual review when operating at scale or in automated CI/CD, script-execution, or sandboxed environments.
Side effects
- Missing 'command' parameter returns an error or empty analysis
- Obfuscated or encoded commands may not be detected correctly
- Very long or complex scripts may exceed input limits
- Novel evasion techniques may be misclassified as low-risk
- Non-shell syntax (Python, PowerShell) may yield inaccurate results
