## _1. Introduction_

_Large Language Models (LLMs) are increasingly embedded into enterprise applications to enable automation, decision support and natural language interfaces. However, direct integration of LLMs into applications introduces significant architectural challenges due to their rapid evolution, variability across providers and non-deterministic behavior._

_These challenges include rising operational cost, security exposure, vendor dependency and lack of governance. As a result, enterprises require a stable abstraction layer to manage and control LLM interactions._

_This is addressed through the_**_AI API Gateway_**_, a governed integration layer that mediates all communication between enterprise applications and LLM providers._

## _2. Scope Boundary_

_This architecture is intentionally scoped to a_**_LLM integratio
