Datadog API Catalog is a unified inventory of all team APIs and their endpoints, providing visibility into the API landscape through Datadog's distributed tracing capabilities. This allows teams to discover their API landscape, monitor endpoint performance and security, establish API ownership and governance, improve API performance and reliability, detect and alert on API issues, and enhance overall API security posture. The catalog integrates with Datadog Synthetic Monitoring, Application Security Management (ASM), and other tools to provide a comprehensive view of APIs, enabling teams to manage standardized, approved, and production-ready APIs within Datadog, monitor their performance and reliability, and quickly identify who owns certain endpoints for faster triage during incidents.
