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.
five (Pentium = fifth-generation Intel CPU)
Lexicon Branding canonical case — Pentium named to differentiate 5th-gen Intel CPU from the '586' that competitors could clone. Placek talks about it on Lenny's pod.
e.g. Pentium · Pentagon
Greek root
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
Confident, open, expansive
A opens the mouth wide. Brands starting with A feel approachable and confident — Amazon, Apple, Asana, Adobe, Atlassian. The open vowel makes a name feel inclusive and platform-like.
e.g. Amazon · Apple · Asana · Adobe · Atlassian
Decisive, definite
D is B's gentler cousin. Decisive but not aggressive. Used in consumer trust brands (Dropbox, Dasani, Dell).
e.g. Dropbox · Dasani · Dell · Duolingo · Discord

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).
e.g. Facebook · Figma · FedEx · Ford · Flickr
Confident, open, expansive
A opens the mouth wide. Brands starting with A feel approachable and confident — Amazon, Apple, Asana, Adobe, Atlassian. The open vowel makes a name feel inclusive and platform-like.
e.g. Amazon · Apple · Asana · Adobe · Atlassian
Fast, crisp, innovation
X is the innovation letter. From X-ray to Tesla Model X, X-prefix signals 'next-generation'. Also a great suffix — Brex, Latex, FedEx, Netflix. The KS-cluster makes any name feel sharper.
e.g. Xerox · Xbox · Tesla Model X · Netflix · Brex

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