check_handle
Check a name on every platform
Check whether a brand name or username is free on X, YouTube, LinkedIn, GitHub, Shopify, Bluesky, Snapchat and more (29 platforms), and on the main domain endings (.com, .ai, .io, .com.au and others). Each platform is only trusted while it still calls a certainly-taken name taken; platforms that refuse checks (Instagram, TikTok, Facebook, Reddit) come back as "check yourself" with a link. Free, no API key needed.
