Take charge of the APIs that drive your digital experience

Due to the rise of microservices, the spread of single page web apps, and the continued dominance of native mobile apps, APIs are the engines that businesses rely on to power their applications and outpace their competition. Beyond their own internally-created APIs, modern companies oftentimes integrate with countless third party APIs for critical business processes.

This combination means it is imperative to ensure the availability, functionality, and performance of all APIs. Gaps in API performance don’t only impact user experience, but also disrupt workflows, hurt brand reputation, and can lead to significant revenue loss.

Rigor’s API Check gives you peace of mind by continuously monitoring all your first and third party APIs to verify the availability, response time, and data quality for these transactions.
