Prices exclude tax and are per extension: a name the registry flags as premium costs more. Rates are read from published registrar tariffs and refreshed daily.

The first year is a promotion

A .io registered at $28.12 renews at $51.80, roughly 1.8 times the entry price. Over five years the promotional year accounts for a small share of what you actually pay, which is why comparing first-year prices tells you almost nothing.

Before you buy: is the name even free?

A price only matters once the domain is available. Onomatix checks that against the registry itself over RDAP — an HTTP 404 means no registration exists — and falls back to WHOIS on port 43 for extensions with no RDAP endpoint. That is a fact, not a cached guess.
