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.
abstract noun ending; in Sanskrit, 'great' or 'mother'
Soft, mother-feeling suffix. Lands warm.
e.g. Figma · Asma · Karma
Latin / suffix root
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
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
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

act of, modern tech connotation via .io domain

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