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.
cloak, covering, role
Concrete + metaphor (assuming the mantle). Earth-science / responsibility register.
e.g. Mantle Climate · Mantle Networks
Old English / Old French root

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
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
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
Generative, grounded, growth
G has weight without aggression. Google's double-G is famously childish-fun and warm. Glossier slips on the G; Granola buries it. Pairs well with -oo for bouba roundness.
e.g. Google · Glossier · Granola · GitHub · Genesis

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