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.
flow, motion
X-ending + F-onset — sharp, sciency feel.
e.g. Influx · Reflux · Fluxion
Latin root

Small, precise, individual
I is the smallest character on the keyboard. Used for personal/lightweight brands (Instagram, iPhone). Apple's i-prefix is the modern naming canon. Front-vowel I makes things feel sharp and small.
e.g. iPhone · Instagram · Intel · Imgur

Bright, technological, small/precise
E reads as 'electronic' to a generation raised on e-commerce. eBay, Etsy, Excel. Front vowels make things feel small and quick.
e.g. eBay · Etsy · Excel · Edison · Equinox
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
Pairs fluxxfilter with classical suffixes (-ex, -ius, -ium, -on), morphemes from the bank (ver-, lex-, pro-), and vowel mutations — then bloom-checks every candidate against the live .com zone file. Up to 400 candidates per click; only the available ones land here.

First-letter feeling
F-onset: Smooth, frictional, friendly
F flows. Less attention-grabbing than B or K, but warm. Facebook, FedEx, Figma — F can either soften the front (Figma) or pair with an explosive ending (FedEx).
Examples: Facebook · Figma · FedEx · Ford · Flickr

How we check. Step 1 (client-side): POST /api/check
with fluxxfilter.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=fluxxfilter.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.
