Public Interface

Relevant primarily to registry operators and developers building public-facing clients.

Web WHOIS

FRED provides a two-layer WHOIS interface consisting of a basic web frontend and an underlying API. This allows registry operators to integrate WHOIS and public request services into their own websites, or to expose them as standalone services.

Unix WHOIS

FRED supports the traditional WHOIS protocol, allowing public information about registry objects to be queried via standard WHOIS clients.

RDAP

FRED supports the Registration Data Access Protocol (RDAP), the modern successor to WHOIS. RDAP provides structured, standardised responses, making it better suited than WHOIS for programmatic access and privacy-aware disclosure policies.

Public interface for registrants

FRED provides a public-facing API that allows registrants to request changes to object states directly, without needing to route those requests through their registrar.

Domain browser

FRED includes a publicly accessible web service that allows authenticated domain registrants to view registry information about the objects they own or administer. The Domain Browser supports OIDC (OpenID Connect) authentication and provides an interface for registrants to request object locks directly, without registrar involvement.
