A growing set of small, fast utility APIs on Cloudflare Workers: link previews, WHOIS/RDAP and DNS lookups, email validation, security-header grades, CORS and robots.txt checks. Free tiers; each one is a single GET call.

Hi Product Hunt! I built these small utility APIs because I kept needing quick checks (DNS records, security headers, CORS, email validation, link previews) without signing up for a heavy platform. Each one is a single GET request running on Cloudflare Workers, based on public protocols (RDAP, DNS-over-HTTPS, RFC standards), and most have a free plan. They are listed on RapidAPI, Zyla API Hub, API.Market and FireAPI, and the repo has curl, Python and JavaScript examples for all ten. I'd love to hear which checks you wish existed next.
