## 📡 How it Works

- The SDK sends your request to the Web2Docx server.
- WebSocket connection is used to listen for **job completion events**.
- Once the server finishes conversion, your promise resolves automatically.
- Queues: Free users are slower; Pro and Pro Max users get faster processing.

---

## 🧹 Notes

- If a job takes more than 60 seconds, it **times out** and throws an error.
- Make sure your API Key is correct and active.
- Currently supports **HTML input only** (URL input coming soon).
