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.
summation, statistical mark
Statistical / data register. Greek-letter prestige.
e.g. Sigma · Six Sigma
Greek root
Breathy, humble, honest
H is the gentlest onset. Hub, Hims, Helio. The breath before the word — used when you want the brand to feel modest or whispered.
e.g. Hims · Hubspot · Honda · Häagen-Dazs
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
Versatile, soft-or-hard depending on next vowel
C is two letters in disguise. CA/CO/CU = K-energy (Coca-Cola, Cisco, CapCut). CE/CI = S-energy (Cellular, Citi). Brands lean one way or the other deliberately.
e.g. Coca-Cola · Cisco · Canva · Calm · CapCut
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 sigmahacax.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=sigmahacax.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.
