API Metrics is a new product by ReadMe that provides comprehensive insights into API usage, enabling users to monitor who is using their API, how frequently, and with what success. This tool comprises two main components: the API Metrics Dashboard and Customer Facing Logs. The dashboard allows admins to filter API logs by criteria such as status code, endpoint, method, and project, offering a segmented overview of usage metrics, status codes, and detailed logs of API calls. These features help in identifying active and inactive users, frequently used endpoints, and potential issues before they arise. The Customer Facing Logs feature lets authenticated users view their API interaction history, aiding in troubleshooting and self-diagnosis. API Metrics is free for up to 10,000 logs per month, with subscription options available for higher usage, and is integrated into ReadMe after defining the API.
