## ⚠️ IMPORTANT NOTES

1. **Local Server Must Be Running**: 
   ```bash
   cd d:\webscreper
   uvicorn api:app --port 7860
   ```

2. **For Hugging Face Deployment**: Replace `http://127.0.0.1:7860` with `https://ubuntu593-alt-scraper-api.hf.space`
   - ⚠️ **Note**: HF deployment needs to be updated first (see deployment guide)

3. **Save Job ID**: Copy the `job_id` from step 3 to use in steps 4 & 5

4. **Polling**: Call step 4 every 1-2 seconds until `status` becomes `done`
