Domain Data API Documentation

The Domain Data API allows querying various domain-related data, including parsing, semantic analysis, WHOIS lookups, and more.

General API Structure

The general API structure follows the format:

https://api.domaindata.net/<version>/<object>/<method>/<format>?key=<APIKEY>

version: The API version (currently v1).
object: The resource object to query (e.g., domain).
method: The requested action (e.g., parse).
format: The output format (json, xml, jsonp with the additional GET parameter ?func=).

Domain Parsing API

Parses domain names into components and normalizes the information.

https://api.domaindata.net/v1/domain/parse/json?domain=blog.example.co.uk&key=123

{
    "status": "ok",
    "cleanHost": "blog.example.co.uk",
    "cleanDomain": "example.co.uk",
    "subDomain": "blog",
    "tld": "co.uk"
}

Semantic Domain Analysis API

Analyzes domain names semantically.

https://api.domaindata.net/v1/domain/analyze/json?domain=autokaufen.com&key=123

{
    "cleanDomain": "autokaufen.com",
    "category": "commerce",
    "keywords": ["auto", "kaufen"],
    "formatted": "AutoKaufen.com"
}

Domain WHOIS API

Retrieves WHOIS information for a domain.

https://api.domaindata.net/v1/domain/whois/json?domain=fahrzeug.com&key=123

{
    "domain": "fahrzeug.com",
    "status": "registered",
    "result": "<<<< RESULT >>>>"
}

If you have high volume WHOIS requests, please contact support. We can offer an async solution for you.

Domain Research API

The Domain Research API collects all available information collected for a certain domain. This is timely process of several minutes. When finished the result is sent to your servers.

https://api.domaindata.net/v1/domain/research/json?domain=xx.de&key=123&callback=https://your-server.de/api/result

{
    "status": "ok"
}

The data is sent as a POST request and has the following structure

{
    "status": "registered",
    "cleanDomain": "xx.de",
    "ips": ["185.244.195.154"],

Reverse Domain Data API

Custom APIs for monitoring domain-related events call your services on certain events.

These APIs notify customers when watched domains become available or when trademarks are registered in new domains. Contact support for more information.
