Frequently asked questions
How do I register a domain?
Search for your domain, choose from 400+ TLDs, and check out in seconds. Registration is instant for most extensions, and every domain includes free WHOIS privacy, DNSSEC, and anycast DNS.
Can I register and manage domains with AI like Claude or ChatGPT?
Yes. OSIR is an AI-native registrar with a Model Context Protocol (MCP) server that exposes 82 tools. Connect Claude, Cursor, or any MCP client to search, register, transfer, and manage domains, DNS, and VPS in natural language.
How much does a domain cost, and are there hidden fees?
Prices vary by TLD, and renewal always equals the registration price - no first-year teaser pricing. A mandatory ICANN fee of $0.20 and a processing fee of 3% or $0.30 (whichever is greater) are shown at checkout. Nothing else.
Can I transfer an existing domain in?
Yes. OSIR supports transfers from all major registrars. Most complete within 5 days and add a full year to your registration, and we email you at every step.
