Whois data manipulation is a pain.

WebCargo provides structured JSON Whois data through a REST API so you can get on with what matters.

Smart cache

Many Whois servers are heavily rate limited so data for some TLDs are cached on our system for one hour. We leverage the collective Whois requests sent to our servers and advanced crawling and re-crawling algorithms to ensure you get speedy and consistent results.

WHOIS intricacies

Public Whois databases lack useful specification making obtaining records from a variety of sources not so straightforward. WebCargo creates a layer of abstraction around the pesky intricacies by handling the format changes and rate limits.

Uniform results

Structured and standardized results mean that you can start manipulating data in the ways you need to build your app, faster.


Quickly create an IP white list for your API key to safeguard from abuse. Audit your usage through our API logs, enabling you stay on top of your usage.
