What are API Monitoring Tools with a Free Trial?

API monitoring tools are software solutions designed to track the performance of an application programming interface (API). These tools can provide insights into API errors, request routing, latency, and other key metrics. They also help identify potential issues such as broken calls or security susceptibilities. Additionally, API monitoring can be used to log all calls made to the API and alert users of any unexpected behaviour. Furthermore, some API monitoring tools are able to recognize trends in user requests that could indicate a need for increased capacity or improved design. Finally, these tools are typically cloud-based and easy to integrate into existing architectures without requiring significant changes.
