If need to check your IP address, http://ifconfig.co/ is a nifty tool. It even has a JSON output: http://ifconfig.co/json
It is hosted behind #CloudFlare, so if you access it using curl via #Tor, you get a CAPTCHA page.
Hilariously, that page contains the IP address you reached the site from. So you still get to check your IP address anyway.
Such protecc. Many wow.
