# Simplifying domains for people and agents

**Type:** Announcement

## Summary

Cloudflare Registrar introduced a redesigned domain search that shows every supported extension and responds progressively as the user types. The search gathers availability evidence from prepared datasets, DNS, and live registry checks, updating only changed results via WebSocket deltas. The system uses Workers, Durable Objects, and Workers KV on Cloudflare’s developer platform to coordinate more than 420 extension checks per query. The Registrar API beta now includes a sandbox for testing, transfer support, and an extensions endpoint with registry requirements. Agents can search, register, or transfer domains through the MCP or the newly launched cf CLI with natural-language prompts.

## Context

Cloudflare Registrar launched a decade ago with domains at cost and no upsells. The new search and API extend that simplicity to the entire discovery and purchase experience for both people and AI agents.

## Approach / What changed

Cloudflare rebuilt its domain search with Workers handling the entry point and evidence-gathering, Durable Objects coordinating each search session, Workers KV storing prepared availability datasets, and Websockets delivering results incrementally via snapshot and delta messages. The API and cf CLI enable agent interactions.

## Takeaways

- Cloudflare Registrar now exposes a sandbox in its API so developers can test domain search, check, and registration workflows without real purchases.
- The new domain search supports 420+ extensions and displays results for the exact searched term across every extension, including already-registered domains.
- Domain availability is determined by progressively probing prepared datasets, DNS, and live registry checks; a hit confirms use but a miss requires a live registry response for authoritative availability.

## FAQ

### How does the new search determine domain availability?

The search gathers evidence from three sources: prepared availability datasets and cached answers, DNS answers, and live registry lookups. A hit from a dataset or DNS shows a domain is in use, but a miss does not prove availability so live checks provide the authoritative answer.

### Can AI agents buy domains through Cloudflare Registrar?

Yes, any agent with access to the Cloudflare MCP or cf CLI can search, register, or transfer domains. The Registrar API and cf CLI expose commands like check, create, and transfer-in that agents call programmatically.
