If you need an extension whose status is confirmed, .ai is the only one of these three that the available official records establish as a delegated top-level domain. It is Anguilla’s country-code TLD (ccTLD), often used to signal an artificial-intelligence connection. The official evidence reviewed does not establish that .agent or .agi is currently delegated and open for public registration, so verify either one in authoritative records before building a brand around it.
How .agent, .agi, and .ai compare
| Extension | Verified status | What to know before choosing |
|---|---|---|
.ai |
Delegated ccTLD managed by the Government of Anguilla. IANA’s delegation record lists nic.ai as the registration-services URL; the record was last updated February 11, 2025. | It can communicate an AI-related brand cue, but it remains a country-code domain, not a generic TLD. The record does not establish whether a particular name is available or what it costs. |
.agent |
Current delegation and public-registration status are not established by the official evidence reviewed. | Check the IANA Root Zone Database and confirm registration availability and terms with the relevant registry or registrar before using it in a launch plan. |
.agi |
Current delegation and public-registration status are not established by the official evidence reviewed. | Check the IANA Root Zone Database and confirm registration availability and terms with the relevant registry or registrar before using it in a launch plan. |
Is .ai a country-code domain?
Yes. IANA classifies .ai as a ccTLD and identifies its manager as the “Government of Anguilla, Ministry of Infrastructure, Communications and Utilities.” The letters are widely recognizable as an artificial-intelligence reference, but that branding association does not change the extension’s registry classification. See IANA’s .AI Domain Delegation Data.
IANA lists nic.ai as the registration-services URL. That entry identifies a relevant registration channel; it is not confirmation that your chosen name is available, nor a price quote.
Can I register a .agent or .agi domain?
The official sources reviewed do not establish either string as a currently delegated, publicly registrable TLD. That is not proof that either could never become available; it means you should not assume you can buy one or treat it as operational based on its appearance in a proposal, application, or news story.

- Used Book in Good Condition
Check the IANA Root Zone Database for current delegated TLDs, then confirm directly with the relevant registry or registrar whether the exact extension and name can be registered and what rules apply. ICANN’s New gTLD Program describes a process for expanding the DNS, including a 2026 round; a prospective string or application is not itself evidence of a live public extension.

Choose .ai when its verified status and brand signal fit
Among these three options, .ai has the clearest confirmed status. It may suit an AI product or company whose audience understands the association, provided the exact name and registration terms work for you. Keep in mind that the extension’s formal status remains Anguilla’s ccTLD.
Do not build a launch around .agent or .agi until verified
Both strings may look relevant to agent technology or artificial general intelligence, but a useful brand interpretation does not establish that an extension exists in the DNS or can be registered. Treat either as unavailable for planning purposes until current authoritative records and a registry or registrar confirm otherwise.
Account for operational and brand risk
A domain is part of the route customers use to find a service. Before adopting an extension with uncertain status, consider what happens to launch timing, email, links, and customer recognition if it cannot be registered or its terms do not fit your needs. Prefer a domain you can secure and renew under known conditions over a more appealing string whose availability is unconfirmed.
Quick Recap
Rank #3
Verify a domain before committing
- Check delegation: Search the IANA Root Zone Database to see whether the extension is currently delegated.
- Confirm registration rules: ICANN explains that gTLD domains are registered through ICANN-accredited registrars or their resellers, while ccTLD domains are registered through their ccTLD operators. Review ICANN’s domain registration guidance and confirm the relevant operator’s rules.
- Check the exact name: Search with the appropriate registration provider; an extension’s delegation does not mean your desired name is available.
- Compare the full contract cost: Check first-year and renewal fees, plus transfer terms, for the exact name. ICANN notes that these terms are governed by your agreement with the chosen registrar; an introductory price alone does not show the ongoing cost. See ICANN’s domain registration process overview.
- Assess fit: Decide whether the extension’s audience signal, registration rules, and expected continuity suit the people who will use the domain.
