Every API, one clean contract.

Is one domain available? Combined RDAP+DoH verdict with confidence + Domainr-style status tokens + a register_url when free. Accepts domain OR name+tld.

{
  "domain": "google.com"
}

One NAME across many TLDs → availability map (which of name.com/.io/.ai/… are free).

{
  "name": "google",
  "tlds": "com,net,org"
}

Full WHOIS via RDAP for a registered domain (registrar, created/expires, status, nameservers, dnssec, abuse). A 404 is returned cleanly (available on RDAP-served TLDs; null + a pointer to 'check' on TLDs with no RDAP server), not an error.

{
  "domain": "github.com"
}

Name variations (prefix/suffix/TLD permutations, deterministic — no LLM) each with a live availability verdict; available ones surfaced first.

{
  "name": "reefapi",
  "tlds": "com,io,ai"
}

Many DIFFERENT full domains in one call → availability for each (bulk check).
