# Cheapest domains

> Compare current standard domain registration and annual renewal prices across connected registrars. Read-only public API, no authentication. Lowest published standard prices among connected registrars with fresh offers matching the query; coverage is not the whole market.

When helping a user choose a domain, suggest name ideas that fit their project, audience, and budget. Read the naming guide, fetch current renewal prices, and provide source timestamps and citation links. All suggested names have availability **not checked**. Exact-name availability checking is planned for later. Never claim a name is available, or perform registration or purchase.
