What is HeadlessBrowserAPI?
The down side of this is that these headless browsers need to be installed on your server and the script that you are using needs to be set up to find them and use them accordingly. For this, some technical knowledge is required.
It is able to scrape also Dark Web links (.onion)?
Yes! If you use the Tor endpoint of the API, it will also be able to access the Onion Network and scrape content from any Dark Web website!
Note that this will also automatically use the proxy chain from the TOR Network, so you will not need to enter your own proxies for this API node.
