API Status Checker
FreeCheck if an API endpoint is live and measure response time
About API Status Checker
Before you debug your own code, it helps to know whether the API you depend on is even up. The API Status Checker pings an endpoint and tells you if it's responding, along with how long the round trip took. It's the quick sanity check you reach for when something downstream feels slow or broken and you need to rule out the service itself.
Enter the endpoint URL and run the check. The tool sends a request and reports whether the endpoint is live plus its measured response time, so you get an immediate read on availability and latency. It's free, runs in your browser, and needs no signup, making it easy to keep open in a tab whenever you're watching an integration or comparing how fast different endpoints respond.
Common uses
- Confirm a third-party API is up before assuming a failing feature is your own bug.
- Measure baseline response time for an endpoint to spot when latency starts creeping up.
- Check whether a freshly deployed service is reachable from the public internet.
- Compare response times across regional endpoints to pick the fastest one.
- Quickly verify a status or health endpoint during an incident.

FAQ
What does the response time measure?
It reflects the round trip from your browser to the endpoint and back, giving you a practical sense of how quickly it responds.
Does a slow result mean the API is down?
Not necessarily. A high response time signals latency, while a failure to respond indicates the endpoint may be unreachable or down.
Can browser restrictions affect the check?
Because the request comes from your browser, endpoints that block cross-origin requests may not report cleanly. Public health endpoints usually work well.
Is it a continuous monitor?
It runs on-demand checks rather than ongoing monitoring, so run it whenever you want a fresh reading.
Can I use API Status Checker on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
