Gartner defines an AI gateway as a technology or platform that acts as an intermediary between applications and various artificial intelligence (AI) services or models. Its purpose is to simplify and manage access to AI capabilities, providing a central point to enable security, governance and observability of AI workloads.
Gartner defines the application programming interface (API) management market as the market for software to manage, govern and secure APIs. APIs modernize IT architectures. They provide context, tools and resources to generative and agentic AI programs and provide access to systems, services, partners and data services. API management tools enable organizations to plan, deploy, secure, operate, version control and retire APIs, regardless of their size, region or industry.
