Domain check
This usually takes about 2 seconds. RDAP catches the case where a domain is registered but currently has no nameservers (expired-redemption, parked, just-registered).
Every phonic in the name carries weight. Here's what each segment does — read left to right.
Sharp, crisp, bright
K is the bouba/kiki experiment's spiky letter. Kodak, Krispy, Kindle. Pairs well with the bouba/kiki rule (cross-cultural — K reads as 'pointy' across languages).
e.g. Kodak · Kindle · Krispy Kreme · Klarna · Klaviyo

Noisy, alert, attention-grabbing
S is what a snake does — hiss for attention. Stripe, Snap, Slack, Spotify, Sonos. The most populous brand-starter letter for that reason. Pairs with anything.
e.g. Stripe · Snapchat · Slack · Spotify · Sonos
Round, bouba, full
O is the bouba/kiki experiment's round letter — across every language tested, a round shape gets associated with O-sound. Cross-cultural roundness. Best for friendly, premium, container/orb brands.
e.g. Sonos · Roku · Volvo · Otto · Onfido
Rolling, robust, ready
R conveys motion and roll. Less smooth than L (English R is more forceful). Used for action brands (Rivian, Roku, Reddit, Ralph Lauren). R also doubles as a sci-fi register (Robocop, R2D2).
e.g. Rivian · Roku · Reddit · Ralph Lauren · Revolut

How we check. Step 1 (client-side): POST /api/check
with kaisorius.com. The function hashes the SLD against our bloom
filter (built daily from the .com zone). Step 2 (only if step 1 said
"not in zone"): GET /api/rdap?domain=kaisorius.com which HEADs
VeriSign's RDAP endpoint to confirm whether the domain is held at the
registry without active nameservers. Neither step logs your query.
