API docs

A free, keyless JSON API for domain availability. Lookups use the registry's RDAP records first, with DNS as fallback.

Endpoint

GET https://z.ah.football/api/public/v1/check?domain={name}

domain (required) — the domain to check, e.g. coolname.io

{
  "domain": "example.com",
  "available": false,
  "status": "taken",
  "source": "rdap",
  "checkedAt": "2026-09-20T03:47:00.000Z"
}

status — "available" | "taken" | "unknown"

source — "rdap" (registry record) or "dns" (fallback)

curl "https://z.ah.football/api/public/v1/check?domain=youridea.dev"

400 — missing or malformed domain

502 — upstream registry/DNS lookup failed, retry
