# Run and deploy your AI Studio app
This contains everything you need to run your app locally.
View your app in AI Studio: https://ai.studio/apps/96002e3b-5eec-4566-85e8-718714e15c2c
## Run Locally
**Prerequisites:** Node.js
1. Install dependencies:
`npm install`
2. Set the `GEMINI_API_KEY` in [.env.local](.env.local) to your Gemini API key
3. Run the app:
`npm run dev`
## Run the API server
The UI runs on port `3000`. The HTTP API runs separately on port `3002`.
1. Set `GEMINI_API_KEY` and `API_AUTH_TOKEN` in `.env.local` or your shell.
2. Start the API:
`npm run api`
3. Check the API:
`http://localhost:3002/api/health`
Example `.env.local`:
```env
GEMINI_API_KEY="YOUR_GEMINI_API_KEY"
API_AUTH_TOKEN="YOUR_LONG_RANDOM_API_TOKEN"
API_PORT="3002"
```
All protected API calls must send one of these headers:
```txt
Authorization: Bearer YOUR_LONG_RANDOM_API_TOKEN
```
or:
```txt
x-api-key: YOUR_LONG_RANDOM_API_TOKEN
```
You can change the server API key without restarting:
```bash
curl -X POST http://localhost:3002/api/config/api-key \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_LONG_RANDOM_API_TOKEN" \
-d "{\"apiKey\":\"YOUR_GEMINI_API_KEY\",\"persist\":true}"
```
You can also pass a temporary Gemini key for one call:
```bash
curl -X POST http://localhost:3002/api/generate \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_LONG_RANDOM_API_TOKEN" \
-H "x-gemini-api-key: YOUR_GEMINI_API_KEY" \
-d "{\"prompt\":\"Create a clean product poster\"}"
```
### API examples
Generate or edit with JSON/base64:
```bash
curl -X POST http://localhost:3002/api/generate \
-H "Content-Type: application/json" \
-H "Authorization: Bearer YOUR_LONG_RANDOM_API_TOKEN" \
-d "{\"prompt\":\"Create a clean product poster for a white coffee mug\",\"imageSize\":\"1K\",\"aspectRatio\":\"1:1\"}"
```
Upload an image or document with a prompt:
```bash
curl -X POST http://localhost:3002/api/generate/upload \
-H "Authorization: Bearer YOUR_LONG_RANDOM_API_TOKEN" \
-F "prompt=Change the background to a bright studio scene" \
-F "imageSize=1K" \
-F "aspectRatio=1:1" \
-F "files=@input.png"
```
Analyze a document:
```bash
curl -X POST http://localhost:3002/api/analyze-document \
-H "Authorization: Bearer YOUR_LONG_RANDOM_API_TOKEN" \
-F "prompt=Summarize this document in Chinese" \
-F "files=@report.pdf"
```
API auth is required by default. For local-only development, you can set `API_AUTH_DISABLED=true`, but do not use that on a LAN or server.
For Agent-facing image generation and editing instructions, see:
- `API图片绘制及修改-Agent.md`: generic/local API usage.
- `API图片绘制及修改-Agent-NAS.md`: NAS usage with `192.168.31.5:4000`.
## Docker Compose Deploy
For Docker Compose deployment, edit `docker_compose.yaml` and fill the `environment` values:
```env
GEMINI_API_KEY="YOUR_GEMINI_API_KEY"
API_AUTH_TOKEN="YOUR_LONG_RANDOM_API_TOKEN"
API_AUTH_DISABLED="false"
API_PORT="3002"
APP_PASSWORD="123456"
APP_URL="http://YOUR_SERVER_IP:3000"
```
Then start:
```bash
docker compose -f docker_compose.yaml up -d --build
```
Default ports:
- UI: `http://YOUR_SERVER_IP:3000`
- API: `http://YOUR_SERVER_IP:3002`
