How we keep your API requests secure

Quick Start

Testing an API endpoint takes just 3 steps:

  1. Enter the API URL you want to test
  2. Select the HTTP method (GET, POST, PUT, DELETE, PATCH)
  3. Add any required headers or body payload
  4. Click "Check Response Time" for instant results

Results include: response time, DNS lookup, TTFB, status code, response size, SSL info, and more.

API Reference

You can use our API programmatically by sending a POST request to /api/check:

POST /api/check
Content-Type: application/json

{
  "url": "https://api.example.com/data",
  "method": "GET",
  "headers": {
    "Authorization": "Bearer token"
  }
}

Security

All API requests are made server-side. This means:

  • Your API keys and tokens are never exposed to the browser
  • Requests are made from our secure infrastructure
  • All communication is encrypted via HTTPS
  • We do not store any request data or responses
