A set of guidelines for designing APIs that are consistent with Google AIPs.
API Improvement Proposals
AIPs are design documents that summarize Google's API design decisions. They also provide a framework and system for others to document their own API design rules and practices.

Introduction
This website describes a way to manage APIs that is inexpensive, high-performing, and surprisingly easy to use. It’s also great for APIs that are built with gRPC and Protocol Buffers. It’s the only API management system that starts with these powerful approaches, and if you are building APIs with them, you’ll find it especially familiar. It emerged from internal API management practices at Google, and as you might hope, it works great on Google Cloud, but it’s not limited to that. We’ll show you how it can be used with or without Kubernetes on any cloud platform and on systems that you run yourself.
OpenAPI 3.x Extensions in API Gateway | Google Cloud Documentation
API Gateway accepts a set of Google-specific extensions to the OpenAPI specification that configure the behaviors of the gateway. These extensions allow you to specify API management settings, authentication methods, quota limits, and backend integrations directly within your OpenAPI document. Understanding these extensions helps you tailor your service behavior and integrate with API Gateway features.

Overview of model routing | API Gateway | Google Cloud Documentation
Model routing for API Gateway is a managed traffic management layer that accepts OpenAI-compatible prompt requests, transcodes them in-flight, and routes them to specific Gemini Enterprise Agent Platform models. Model routing acts as a managed alternative to client-side proxies such as LiteLLM, providing centralized infrastructure to manage the lifecycle of AI agents.

Google Cloud API Gateway now offers a model routing feature in Public Preview, allowing developers to dynamically route traffic to models like Gemini, Claude, or OpenAI OSS-GPT without hardcoding endpoints or managing open-source proxies. Developers can easily configure these routing rules directly within their OpenAPI 3.x specifications by mapping virtual model names to specific backend targets on a shared host. Once deployed, the Gateway acts as a serverless ingress layer that accepts standard OpenAI-compatible requests, automatically transcodes the payload to the native schema of the target model, and routes the traffic on the fly.
