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
Curious, distinctive, rare
Q is rare. Just appearing at the start of a brand creates distinctiveness. Quibi, Quartz, Quora, Quad. The Q itself is the mnemonic.
e.g. Quora · Quartz · Quibi · Quizlet

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
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
Pairs pentqoolbox 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
P-onset: Punchy, popping, percussive
P pops. Plays well with concrete object names — Pepsi, Pixar, PowerBook, Pentium. Lexicon canonical: PowerBook = compound, Pentium = morpheme + suffix.
Examples: Pepsi · Pixar · PowerBook · Pentium · Polaroid · Pinterest
Morpheme breakdown — 1 root detected in pentqoolbox

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