FAQ
What does this API checker do?
It sends a real HTTP request to your API URL and returns the status code, response time, response headers, and a preview of the response body — immediately, no sign-up required.
Which HTTP methods are supported?
GET, POST, PUT, DELETE, PATCH, HEAD, and OPTIONS. Select the method from the dropdown before checking.
Is this different from ping or uptime monitoring?
Yes. A ping only checks if a host is reachable. This checker makes a real HTTP request and shows you the full response — status code, headers, and body — so you can see exactly what your API returns.
What is the difference between this tool and CheckAPI monitoring?
This tool checks your API once, right now. CheckAPI monitoring checks it automatically every 5 minutes (free plan) and sends you an alert via Slack, Email, or Telegram when something breaks — even at 3am.
How do I get alerted when my API goes down?
Create a free CheckAPI account, add your API as a monitor, and connect an alert channel (Email, Slack, Telegram, Discord, or Webhook). You'll be notified within minutes of any failure.
