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.

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.

Titan in depth: Security in plaintext | Google Cloud Blog
While there are no absolutes in computer security, we design, build and operate Google Cloud Platform (GCP) with the goal to protect customers' code and data. We harden our architecture at multiple layers, with components that include Google-designed hardware, a Google-controlled firmware stack, Google-curated OS images, a Google-hardened hypervisor, as well as data center physical security and services.

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.
