API Lifecycle Management

The practice of governing an API from its initial design through to deprecation, covering documentation, versioning, testing, cataloguing, and enforcing standards across an organisation's full set of APIs. As more software communicates via APIs, including AI agents and integrated platforms, having a structured approach to managing that catalogue becomes critical for consistency, security, and discoverability. API lifecycle management tools typically provide a single place to define, review, publish, and monitor APIs across teams.
