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.
tranquility
Soft trio K+L+M — Calm app is a category-defining naming choice for meditation.
e.g. Calm · Calmly
English (Romance via Latin cauma) root
Deep, you, communal
U is communal — Uber, YouTube, Yum!. Also reads as 'you' in product brands (Unsplash, Udemy).
e.g. Uber · YouTube · Udemy · Unilever · Unsplash
Bold, blunt, declarative
B explodes from the lips. It commits. BlackBerry pairs the bold B with a homely real-word (berry) and the multiplier is the surprise. Brex doubles down — B + X both at the edges. Bumble takes B and makes it cuddly.
e.g. BlackBerry · Brex · Bolt · Bumble · Block
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
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
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
Pairs calmuboxes 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.

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