Icanhazip
A famously minimal service: a GET request to icanhazip.com returns nothing but your public IP address as plain text - no JSON wrapper, no key, no signup. Created by sysadmin Major Hayden and still running behind Cloudflare today (confirmed live, open CORS header), with a dedicated ipv4.icanhazip.com subdomain for forcing IPv4 - it's one of the originals that popularized the curl-your-own-IP one-liner.
