Cloudflare releases beta API for automated domain registration

Cloudflare has announced the Registrar API is now in beta, enabling developers to search for domains, check availability, and register them programmatically as part of the registrar’s at-cost pricing model. The beta focuses on the core moments of the domain lifecycle and is designed to be machine-friendly, with three core actions: search, check, and register, which can be used inside editors, deployment pipelines, backend services, and agent-driven workflows.

The API is part of the full Cloudflare API and can be accessed today through the Cloudflare MCP, with Cursor and other MCP-compatible environments able to call Registrar endpoints using the same search and execute pattern. In practice, a typical flow involves an agent suggesting names, confirming registrable options and price, and then completing the purchase within seconds; the API also supports a 202 Accepted workflow URL if registration takes longer.

Premium domains, when supported, return the exact registry-set price in the check response and echo that as a fee acknowledgement during registration. Development of the broader registrar‑as‑a‑service offering is planned for later this year, with aims to cover transfers, renewals and more. 15 April 2026.
