The API was launched more than four years ago, under the name UserAgent API. As the API became popular with developers around the world, apilayer overhauled the API and upscaled it to fit enterprise requirements such as a 99.9% SLA, 256-bit SSL encryption and dedicated support.

Today, userstack is a scalable API, capable of meeting even the most demanding requirements. Whether it’s a product landing page with a few hundred requests per day or a complex shopping platform with one million requests per month, userstack can handle any scenario. Accenture, Apple or Intuit are some of the prominent brands which are using the userstack API in their products and tools.
