Api Health Check

What This Skill Does

The API Health Check skill serves as a robust diagnostic tool for monitoring the availability and performance of web services. It automatically probes specified API endpoints to determine whether they are operational, sluggish, or unreachable. By executing systematic curls against target URLs, the agent measures latency, inspects HTTP response codes, and evaluates download sizes. It provides a clean, visual representation of endpoint health, identifying issues like timeouts or connectivity failures instantly. Designed for reliability, the skill also includes advanced diagnostic capabilities, such as performing DNS lookups with dig and testing port availability via nc, allowing developers to pinpoint exactly where an infrastructure failure is occurring.

Installation

To integrate this skill into your OpenClaw environment, execute the following command in your terminal: clawhub install openclaw/skills/skills/sa9saq/api-health-check Ensure that you have curl installed on your host machine, as it serves as the primary engine for this skill. While dig and nc are optional, they are highly recommended for the comprehensive troubleshooting workflow.

Use Cases

This tool is ideal for DevOps engineers and developers who need to verify microservice availability in real-time. Use it to monitor production health, debug integration issues between internal services, or establish a baseline for API performance. It is particularly helpful during deployments to verify that new code changes haven't introduced latency or broken connectivity to vital endpoints.

Example Prompts

1. "Perform a health check on https://api.production.com and test common paths like /health and /api/status."
2. "Monitor the endpoint https://internal.service.dev every 30 seconds and alert me if the response time exceeds 2 seconds."
3. "Why is my server returning a 503? Please run a diagnostic check on https://my-service.com including DNS and port verification."

Tips & Limitations

To maximize the utility of this skill, utilize the --watch functionality for continuous monitoring of unstable environments. Always be mindful of the built-in SSRF protection; if you are monitoring private infrastructure, you must provide explicit confirmation to the agent when prompted. Note that the skill automatically masks sensitive information; ensure your custom headers are defined but understand they will be redacted in logs for your protection. If checking numerous endpoints, the agent adds a mandatory 1-second delay to comply with standard rate-limiting practices.
