DNSMint – Give a sandbox its own domain and HTTPS cert in one API call
One API call gives a sandbox its own domain, HTTPS cert and DNSSEC
DNSMint issues a hostname on a dedicated domain plus DNS-01 credentials for certificate renewal, all from a single API call, for short-lived things like sandboxes, CI previews and containers that need real HTTPS without a person configuring DNS. Every domain is DNSSEC-signed before it serves traffic, so a validating resolver rejects a spoofed answer from the start rather than whenever someone remembers to enable it. It works with Caddy, Traefik, certbot, lego, cert-manager and acme.sh via an API key alone, and ships a single plain-text reference file so an AI agent running curl can wire it up itself.
What holds up
- +DNSSEC-signed from the first query, not enabled later as an afterthought
- +Dedicated domain per account — no shared blocklist or certificate budget from other tenants
- +One plain-text reference file lets an agent like Claude Code wire it up via curl alone
- +Hostname is repointable by IP, so a moved machine keeps the same URL working
Mind the limits
- −Built for ephemeral infrastructure — not positioned for permanent, human-facing domains
