Methodology
How domain availability checks work
A brand recommendation is useful only when its meaning and acquisition path are both clear. Here is how aidomains.app builds a comparable naming strategy—and where every availability check still has limits.

01 / Generate
Create brands before domain variants
Your naming brief is used to generate a varied set of canonical brand concepts. Domain endings are not mixed into that creative step. The service then normalizes labels, removes duplicates and invalid forms, and applies explicit brief constraints.
Generation is brainstorming, not evidence of availability. Every surviving brand is checked separately on every primary domain ending before any fallback is planned.
02 / Check
Ask for precise registry-level status
aidomains.app checks candidates individually through the Fastly Domain Research API using its precise status scope. Fastly documents this as a registry-level availability check for new registrations—not a simple DNS lookup.
- Available: the returned status includes
inactive, which Fastly defines as available for a new registration. - Premium: the registry or an aftermarket source reports premium or explicitly marketed inventory. It remains visible as an acquisition option, with quoted pricing shown when the provider supplies it.
- Unavailable: the name is active, parked, claimed, reserved, disallowed, or otherwise not available for a standard new registration.
- Unknown: the provider cannot determine an authoritative status. Unknown and failed checks are never presented as available.
03 / Rank
Rank every brand against the same evidence
AI evaluates semantic fit, pronunciation, spelling, distinctiveness, future-proofing, domain-path quality, and cost, with short evidence. It does not choose the final order. Deterministic application code publishes their rounded mean as the overall score and ranks higher scores first, using acquisition tier and stable rules only to break ties. Brands without a viable path remain visible instead of disappearing.
