Domain Availability checks if a domain name is already registered across many top-level domains by querying their authorities, prioritizing RDAP and falling back to WHOIS. It provides a clear three-state result: available, registered, or unknown.
Domain Availability checks whether a domain name is registered across many top-level domains in a single parallel sweep, using RDAP first and falling back to WHOIS. It never guesses: a lookup that no authority can answer is reported as "unknown", never as "available".
Features
- Parallel availability lookups across every configured TLD in one request.
- RDAP and WHOIS with automatic server discovery from the IANA bootstrap, cached.
- A three-state result — available, registered, unknown — availability is never assumed.
- Pluggable providers via the
domain_availability_providerservice tag. - Response caching, per-client rate limiting, and a JSON API endpoint.
- An optional Saudi domain registration-request workflow.
Post-Installation
