A service catalog empowers API product owners by providing a centralized resource for managing and governing APIs, enhancing discovery, governance, and compliance, streamlining lifecycle management, improving developer experience, and driving strategic decision-making. While maintaining an API Service Catalog can be resource-intensive, it offers significant benefits over decentralized approaches or lightweight solutions, which may lead to fragmentation and inefficiency as teams scale. By leveraging a service catalog, organizations can unlock the full potential of their API strategy, ensuring consistent quality, collaboration, and innovation across teams and stakeholders.
