Overview
Cloudflare Registrar
At-Cost Registrar with Beta API Workflows
Cloudflare Registrar charges registry list prices and offers a beta API for search, authoritative availability and pricing checks, and registration on supported extensions. Checks can surface premium pricing, but the beta does not currently support premium registration. Future support will require explicit fee acknowledgement. Renewals, transfers, and contact updates are not yet available in the beta.
No separate API fee; registration is billableHost.io
Domain Intelligence and Technology Detection API
Host.io focuses on technology fingerprints, related-domain discovery, DNS data, and web market intelligence rather than registrar workflows.
