REST API Testing


Whether it’s running single REST API testing or monitoring complex sequences of REST APIs, APImetrics lets you run REST API tests with real-time alerts, see performance change notifications, and get powerful metrics from around the world and the cloud.

Designed for any REST API or SOAP API 

Fast and easy REST API testing


Just 3 steps to get up and running…

1. Setup

Setup rest API test flows easily and simply or import them directly from Open API specs or Postman.

2. Schedule

Run REST API tests regularly from over 80 different cloud locations at intervals to your chosing.

3. Report and Inform

Create reports and share data to other users or stakeholders instantly and with total security.

Cross Cloud from 80+ locations

Your customers aren't on one cloud, why test from only one? Schedule APIs from any public AWS, Azure, Google or IBM location

Set Conditions & assertions

Create and manage custom conditions for your APIs - set alerts based on speed, size, content & more

Quality & SLAs

Integrated reporting, quality metrics and SLA reporting with API and CSV export.

From just $15 per month
