-# Gemini ↔︎ OpenAI Proxy
+# Gemini CLI OpenAI API Proxy
 
-Serve **Google Gemini 2.5 Pro** (or Flash) through an **OpenAI-compatible API**.  
+This project provides a lightweight proxy server that translates OpenAI API requests to the Google Gemini API, utilizing the `@google/gemini-cli` for authentication and request handling.
-Plug-and-play with clients that already speak OpenAI—SillyTavern, llama.cpp, LangChain, the VS Code *Cline* extension, etc.
 
----
+## Features
 
-## ✨ Features
+* **OpenAI API Compatibility:**  Acts as a drop-in replacement for services that use the OpenAI API format.
+* **Google Gemini Integration:** Leverages the power of Google's Gemini models.
+* **Authentication:** Uses `gemini-cli` for secure OAuth2 authentication with Google.
+* **Docker Support:** Includes `Dockerfile` and `docker-compose.yml` for easy containerized deployment.
+* **Hugging Face Spaces Ready:** Can be easily deployed as a Hugging Face Space.
 
-| ✔ | Feature | Notes |
+## Support the Project
-|---|---------|-------|
-| `/v1/chat/completions` | Non-stream & stream (SSE) | Works with curl, ST, LangChain… |
-| Vision support | `image_url` → Gemini `inlineData` | |
-| Function / Tool calling | OpenAI “functions” → Gemini Tool Registry | |
-| Reasoning / chain-of-thought | Sends `enable_thoughts:true`, streams `<think>` chunks | ST shows grey bubbles |
-| 1 M-token context | Proxy auto-lifts Gemini CLI’s default 200 k cap | |
-| CORS | Enabled (`*`) by default | Ready for browser apps |
-| Zero external deps | Node 22 + TypeScript only | No Express |

+
+[liberapay-logo]: https://liberapay.com/assets/widgets/donate.svg "Liberapay Logo"
+[liberapay-link]: https://liberapay.com/sfiorini/donate
+
+## Prerequisites
+
+Before you begin, ensure you have the following installed:
+
+* [Node.js](https://nodejs.org/) (v18 or higher)
+* [npm](https://www.npmjs.com/)
+* [Docker](https://www.docker.com/) (for containerized deployment)
+* [Git](https://git-scm.com/)
+
+## Local Installation and Setup
+
+1. **Clone the repository:**
+
+    ```bash
+    git clone https://github.com/your-username/gemini-cli-openai-api.git
+    cd gemini-cli-openai-api
+    ```
+
+2. **Install project dependencies:**
+
+    ```bash
+    npm install
+    ```
+
+3. **Install the Gemini CLI and Authenticate:**
+
+    This is a crucial step to authenticate with your Google account and generate the necessary credentials.
+
+    ```bash
+    npm install -g @google/gemini-cli
+    gemini auth login
+    ```
+
+    Follow the on-screen instructions to log in with your Google account. This will create a file at `~/.gemini/oauth_creds.json` containing your authentication tokens.
+
+4. **Configure Environment Variables:**
+
+    Create a `.env` file by copying the example file:
+
+    ```bash
+    cp .env.example .env
+    ```
+
+    Open the `.env` file and set the following variables:
+
+    * `PORT`: The port the server will run on (default: `11434`).
+    * `API_KEY`: A secret key to protect your API endpoint. You can generate a strong random string for this.
+
+## Running the Project
+
+### Development Mode
+
+To run the server in development mode with hot-reloading:
 
 ```bash
-git clone https://huggingface.co/engineofperplexity/gemini-openai-proxy
+npm run dev
-cd gemini-openai-proxy
+```
-npm ci                        # install deps & ts-node
 
-# launch on port 11434
+The server will be accessible at `http://localhost:11434` (or the port you specified).
-npx ts-node src/server.ts
-Optional env vars
-PORT=3000 change listen port
-GEMINI_API_KEY=<key> use your own key
 
-Minimal curl test
+### Production Mode
-bash
-Copy
-Edit
-curl -X POST http://localhost:11434/v1/chat/completions \
-     -H "Content-Type: application/json" \
-     -d '{
-       "model": "gemini-2.5-pro-latest",
-       "messages":[{"role":"user","content":"Hello Gemini!"}]
-     }'
-SillyTavern settings

-API Base URL	http://127.0.0.1:11434/v1
-Model	gemini-2.5-pro-latest
-Streaming	On
-Reasoning	On → grey <think> lines appear
 
-🐳 Docker
+To build and run the server in production mode:
-bash
-Copy
-Edit
-# build once
-docker build -t gemini-openai-proxy .
 
-# run
+```bash
-docker run -p 11434:11434 \
+npm run build
-           -e GEMINI_API_KEY=$GEMINI_API_KEY \
+npm start
-           gemini-openai-proxy
+```

+## Docker Deployment
-Copy
+
-Edit
+### Using Docker Compose
-src/
+
-  server.ts        – minimalist HTTP server
+The easiest way to deploy the project with Docker is by using the provided `docker-compose.yml` file.
-  mapper.ts        – OpenAI ⇄ Gemini transforms
+
-  chatwrapper.ts   – thin wrapper around @google/genai
+1. **Authentication:**
-  remoteimage.ts   – fetch + base64 for vision
+
-package.json       – deps & scripts
+    The Docker container needs access to your OAuth credentials. You have two options:
-Dockerfile
+
-README.md
+    * **Option A (Recommended): Mount the credentials file.**
-📜 License
+        Uncomment the `volumes` section in `docker-compose.yml` to mount your local `oauth_creds.json` file into the container.
-MIT – free for personal & commercial use.
+
+        ```yaml
+        volumes:
+          - ~/.gemini/oauth_creds.json:/root/.gemini/oauth_creds.json
+        ```
+
+    * **Option B: Use environment variables.**
+        If you cannot mount the file, you can set the `ACCESS_TOKEN`, `REFRESH_TOKEN`, and `EXPIRY_DATE` environment variables in the `docker-compose.yml` file. You can get these values from your `~/.gemini/oauth_creds.json` file.
+
+2. **Configure `docker-compose.yml`:**
+
+    Open `docker-compose.yml` and set the `API_KEY` and other environment variables as needed.
+
+3. **Start the container:**
+
+    ```bash
+    docker-compose up -d
+    ```
+
+    The server will be running on the port specified in the `ports` section of the `docker-compose.yml` file (e.g., `4343`).
+
+### Building the Docker Image Manually
+
+If you need to build the Docker image yourself:
+
+```bash
+docker build -t gemini-cli-openai-api .
+```
+
+Then you can run the container with the appropriate environment variables and volume mounts.
+
+## Hugging Face Spaces Deployment
+
+You can deploy this project as a Docker Space on Hugging Face.
+
+1. **Create a new Space:**
+    * Go to [huggingface.co/new-space](https://huggingface.co/new-space).
+    * Choose a name for your space.
+    * Select "Docker" as the Space SDK.
+    * Choose "From scratch".
+    * Create the space.
+
+2. **Upload the project files:**
+    * Upload all the project files (including the `Dockerfile`) to your new Hugging Face Space repository. You can do this via the web interface or by cloning the space's repository and pushing the files.
+
+3. **Configure Secrets:**
+    * In your Space's settings, go to the "Secrets" section.
+    * Add the following secrets. You can get the values for the first three from your `~/.gemini/oauth_creds.json` file.
+        * `ACCESS_TOKEN`: Your Google OAuth access token.
+        * `REFRESH_TOKEN`: Your Google OAuth refresh token.
+        * `EXPIRY_DATE`: The expiry date of your access token.
+        * `API_KEY`: The secret API key you want to use to protect your endpoint.
+        * `PORT`: The port the application should run on inside the container (e.g., `7860`, which is a common default for Hugging Face Spaces).
+
+4. **Update Dockerfile (if necessary):**
+    * The provided `Dockerfile` exposes port `4343`. If Hugging Face requires a different port (like `7860`), you may need to update the `EXPOSE` instruction in the `Dockerfile`.
+
+5. **Deploy:**
+    * Hugging Face Spaces will automatically build and deploy your Docker container when you push changes to the repository. Check the "Logs" to monitor the build and deployment process.
+
+Your Gemini-powered OpenAI proxy will now be running on your Hugging Face Space!
