Why use our Domain availability API
Fresh and reliable
We have spent a long time building an API to provide up to date data which is served in a consistently formatted Json object. We are, however, never done developing. We are constantly expanding and improving upon our API offerings.
Have a REST(ful API)
Our API is wrapped in frustration free packaging to allow you to implement it with ease and speed. To consume any of our services simply perform a single HTTP GET request to our servers, no special headers required. Check out our documentation to learn how our developer first approach will benefit you.
Security through whitelisting
We follow security best practices for our services and we've built in tools to help you secure and audit your app too. Instantly setup an IP address whitelist for your API key to ensure that your key can only ever be used by your servers. Audit your usage through our browseable API logs, letting you stay on top of your usage.
Unlimited access through abstraction
A public whois database is a blessing, the lack of specification surrounding it is a curse. The JsonWhois API protects you from the pesky intricacies of the whois protocol. This allows you to get on with building your awesome app while we maintain the backbone it's built on by handling format changes and rate limits.
