# Setting Up API Tokens for Hugging Face & OpenAI in Hugging Face Space
## 1. Create Required Tokens
1. **Hugging Face Token**:
- Log in to [Hugging Face](https://huggingface.co)
- Go to Settings → Access Tokens
- Click "New token"
- Name your token and select permissions
- Copy the token
2. **OpenAI API Key**:
- Log in to [OpenAI](https://platform.openai.com)
- Go to API settings
- Create new API key
- Copy the key
## 2. Add Tokens to Space Settings
1. Go INTO your Hugging Face Space settings (⚙️ icon)
2. Find "Variables and secrets" section
3. Add tokens as "New secret" one by one:
```toml
MONGO_URI = "your_mongo_uri"
HUGGINGFACEHUB_API_TOKEN = "your_huggingface_token_here"
OPENAI_API_KEY = "your_openai_key_here"
```
## 3. Access Tokens in app.py
```python
import os
# Load environment variable(s)
HUGGINGFACEHUB_API_TOKEN = os.getenv("HUGGINGFACEHUB_API_TOKEN")
OPENAI_API_KEY = os.getenv("OPENAI_API_KEY")
```
## Alternative Methods
### Using Streamlit secrets.toml
```toml
# .streamlit/secrets.toml
HUGGINGFACEHUB_API_TOKEN = "your_token_here"
OPENAI_API_KEY = "your_key_here"
```
## Security Best Practices
- Never commit tokens to version control
- Add `.env` or `secrets.toml` to `.gitignore`
- Use read-only tokens when possible
- Regularly reresh your API keys
- Set appropriate token permissions
