I'm looking for list of public socks proxies in the plain text or another format which can be imported via curl.

I'm aware I could extract it using script such as:

$ pup -f <(curl -sL https://www.socks-proxy.net/) '#proxylisttable tr td:nth-child(1),td:nth-child(2) text{}'

but it doesn't work as expected, so I'm looking for up-to-date open data in easy to read format.

Similar to how I can extract my IP address, like:

$ curl ifconfig.co
192.168.0.x

or:

$ curl ifconfig.co/json
{"ip":"192.168.0.x","ip_decimal":1406000000,"country":"X","country_iso":"GB","city":"Y","hostname":"example.com"}

so the proxy list should be in the plain text, XML/HTML, JSON or YAML format.
