# 3DAI API Backend

A FastAPI backend for 3D AI model generation services.

## Features

- User authentication with Supabase
- Image-to-3D conversion using Meshy AI
- Text-to-3D conversion
- Credit system for usage tracking
- Stripe integration for payments

## Environment Variables

Create a `.env` file with the following variables:

```
SUPABASE_URL=https://<your-supabase>.supabase.co
SUPABASE_KEY=<your-supabase-service-role-key>
JWT_SECRET_KEY=<your-jwt-secret-key>
OPENAI_API_KEY=<your-openai-api-key>
STRIPE_SECRET_KEY=<your-stripe-secret-key>

# Development Mode (for testing without Google login)
DEV_MODE=false
DEV_SECRET_TOKEN=dev-secret-token-change-this
DEV_USER_EMAIL=your-dev-user@example.com
DEV_USER_ID=cc310cdf-83af-48e4-a341-d6c2f3b5462d
```

## Development Mode Authentication

For local development and testing, you can bypass the normal Google OAuth flow using development mode:

1. Set `DEV_MODE=true` in your `.env` file
2. Set `DEV_SECRET_TOKEN` to a secure token of your choice
3. Set `DEV_USER_EMAIL` to the email of an existing user in your Supabase database
4. Set `DEV_USER_ID` to `cc310cdf-83af-48e4-a341-d6c2f3b5462d` (or leave unset to use default dev ID)

**Usage:**
When DEV_MODE is enabled, you can authenticate by sending the dev token in the Authorization header:
```bash
curl -H "Authorization: Bearer your-dev-secret-token" http://localhost:7860/protected-endpoint
```

**Security Note:** Only use this in development! Never enable DEV_MODE in production.

## Local Development

1. Install dependencies:
```bash
pip install -r requirements.txt
```

2. Run the development server:
```bash
uvicorn main:app --host 0.0.0.0 --port 7860 --reload
```
