SatsDNS: DNS hosting, secondary DNS and dynamic DNS paid in sats

Authoritative DNS hosting for domains you already own (DNSSEC-signed, JSON record API, 60 s minimum TTL), secondary DNS for zones on your own primary, and dynamic-DNS hostnames under dynkite.com. Paid per order in sats, no account or API key: an unpaid POST gets HTTP 402 with an L402 challenge (WWW-Authenticate) and a Cashu NUT-24 payment request (X-Cashu); pay either and repeat the request. Every request is checked for free first, so a request that would fail gets a 4xx and no invoice. A free Nostr account (NIP-98) can also order with a Lightning invoice or a bitcoin address, and register .com/.net/.org domains. Routes (POST JSON on https://api.satsdns.com): - /v1/ddns/create/30d: dynamic-DNS hostname, 200 sats (1 year 2,000) - /v1/zones/create/30d: hosted DNS zone, 500 sats (1 year 5,000) - /v1/secondary/create/30d: secondary DNS zone, 500 sats (1 year 5,000) - /v1/zones/renew/30d, /v1/ddns/renew/30d: renewals; /v1/zones/queries/1m: 1,000,000 more queries, 200 sats - Management routes, /v1/info and /healthz: free The listed URL answers GET with the 402 price only; the real call is a POST with a JSON body such as {"hostname": "myhost"}. Nameservers ns1.satsdns.com and ns2.satsdns.com. No email or KYC for DNS hosting, no stored balance, nothing renews automatically.
