Site Load Time API features

Timing Metrics

We break down the total load time into specific phases: DNS Lookup, TCP Connection, TLS Handshake, and TTFB.

Status Codes

Get the HTTP response code (200, 301, 404, 503) to diagnose why a site might be failing.

Redirect Tracing

With the followRedirect parameter, our API chases the redirect chain to the final destination, reporting the status of the actual landing page.

Global Proxy Support

Use the proxyCountry parameter to route requests through different locations, helping you detect geo-blocking or regional downtime.

Lightweight Monitoring

This API uses lightweight HTTP requests, making it perfect for high-frequency monitoring without overloading your server.

Response Headers

Inspect the raw server response. We return the complete HTTP headers to verify security configurations.

Frequently Asked Questions

What does the followRedirect parameter do?
When set to true, the API will automatically follow HTTP 301/302 redirects until it reaches the final destination URL and return the status code of that final page.

Can I check if a site is down in a specific country?
Yes. By using the proxyCountry parameter, you can route the request through different countries to see if the website is inaccessible in specific locations.

What is TTFB?
TTFB (Time To First Byte) is the time it takes for the server to send the first byte of data after a request.

Can I use this for uptime monitoring?
Absolutely. Since it returns the HTTP Status Code (e.g., 200, 404 or 500), it is the standard way to build an uptime monitor.

How much does an uptime check cost?
Checking site status consumes only 1 credit per request.
