Domain Parser API

Parse any hostname or URL with the Public Suffix List. Split a domain into its subdomain, registrable domain (eTLD+1) and public suffix (eTLD), or fetch just the suffix or just the registrable domain. Handles full URLs, internationalized (punycode) domains, IP addresses, multi-level suffixes like co.uk and com.au, and — when you ask for it — private suffixes such as github.io and s3 buckets. Built on an always-current Public Suffix List and served entirely in-memory, so responses are instant and the service is always available. Ideal for cookie and domain scoping, analytics attribution, email and link validation, security and anti-abuse, and devops tooling.
