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.

Found Geekflare API to get markdown from URL for my AI agents. It is fast and cheaper and works on almost every website.

I've been using Geekflare for both their API tools and their multi-AI chat platform. The URL-to-Markdown API has been a game changer for my content pipeline.

Finally found a screenshot API that handles full-page captures correctly. Most others mess up the rendering of dynamic elements. Geekflare API captures the whole thing.

If you are a developer building RAG pipelines, you need this. The URL to Markdown feature is much cheaper than the other big players in this space. It handles dynamic JS-heavy sites surprisingly well.

Frequently Asked Questions

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.

Yes. By using the proxyCountry parameter, you can route the request through different country to see if the website is inaccessible in specific locations.

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

Absolutely. Since it returns the HTTP Status Code (e.g., 200, 404 or 500), it is the standard way to build an uptime monitor.

Checking site status consumes only 1 credit per request.
