## Documentation

# Deploy and Host Gemini CLI into  Claude & OpenAI on Railway

Gemini API Gateway is a self-hosted AI gateway that converts **Gemini CLI** into **OpenAI, Gemini Native, and Claude-compatible REST APIs**. It provides OAuth credential management, automatic credential rotation, streaming responses, multimodal support, image generation, and a powerful web dashboard, making it easy to integrate Gemini into any AI application, automation workflow, or developer tool.

## About Hosting Gemini CLI to API

Deploy Gemini API Gateway on Railway in minutes with a production-ready Docker setup. The gateway exposes standardized OpenAI, Gemini Native, and Claude-compatible endpoints while automatically managing Google OAuth credentials, load balancing requests across multiple accounts, monitoring credential health, and retrying failed requests. It supports real-time streaming, multimodal inputs, image generation, proxy configuration, and both SQLite and MongoDB storage. Whether you're building AI assistants, chatbots, automation tools, or internal developer platforms, Railway provides a simple, scalable environment for running your own secure AI gateway.


## Common Use Cases

- Build applications using the OpenAI SDK while powered by Google Gemini.
- Host a unified API for OpenAI, Gemini Native, and Claude-compatible clients.
- Deploy AI assistants, chatbots, automation workflows, and internal AI tools.
- Manage multiple Google OAuth credentials with automatic rotation.
- Enable streaming, multimodal AI, and image generation through one API.
- Self-host a secure AI gateway for production workloads.
