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

The legality varies by jurisdiction. You should only scan networks, domains, or IPs that you own or have explicit permission to audit. Unauthorized scanning can be considered a cyberattack.

The API attempts to establish a TCP connection to the specified ports on the target IP or hostname. It analyzes the response to determine if the port is open or closed.

If no parameters are provided, the API defaults to scanning the Top 100 most common ports.

To avoid being flagged by IDPS, ensure you are only scanning assets you have authorization for.
