   Using Cloudflare 1.1.1.1 DNS over HTTPS API to bulk search domain TLDs▲11

   I found out Cloudflare has a DNS over HTTPS api via 1.1.1.1 resolver, figured I'd make a small tool out of it, as somene who keeps checking domain names for side projects which I never build, this kinda helps me look for something. It's not fully accurate, because it returns unavailable even for parked pages, which technically are available, but works for me. It just checks for A records via this endpoint https://cloudflare-dns.com/dns-query?name=${domain}&type=A Just make sure to pass this header - "application/dns-json"

    I made an AI-based domain name generator with availability check▲25

    This project came from my own personal need. There are many AI based domain name generators on the market but most of them don't check for availability. Hopefully it helps someone else.
