Five signs you need a premium DNS service

An API that's comprehensive, flexible, and easy to use

One API, all of NS1

Our entire solution is served by one API, so you can manage every part of your network infrastructure using the same set of commands, even as you scale

Developer experience

DevOps teams expect an API that matches their velocity. We put a lot of effort into documenting our API, so even the most complex API-related tasks are simple to implement


NS1’s REST API uses simple key/header-based authentication. Make API calls easily from any language or even the shell

Features of the NS1 API

Speedy automatic propagation

NS1’s global network propagates changes through our API in seconds, eliminating the risk of broken applications and user experiences

Capacity for days

On an average day, NS1 handles between two and four million API calls. We’ve seen individual customers make 2.5m DNS changes through our API on high traffic days, which we handle with plenty of capacity to spare

API-based traffic steering

With NS1, you can route DNS traffic by plugging data feeds into our API - a more flexible, programmable option than using the DNS protocol itself

Terraform & OctoDNS integration

NS1’s global network propagates changes through our API in seconds, eliminating the risk of broken applications and user experiences
