+## 🔐 API Access Notes
+
+This app currently uses the **[Frankfurter API](https://www.frankfurter.app/)**, which is free and does **not** require an API key.  
+If this changes in the future, follow these steps:
+
+1. **Check the official docs:** [frankfurter.app/docs](https://www.frankfurter.app/docs)  
+2. **If an API key is required**:
+   - Register for one on their website
+   - Update the API call in your code:
+     ```python
+     url = f"https://api.frankfurter.app/latest?amount={amount}&from={from_curr}&to={to_curr}&apikey=YOUR_API_KEY"
+     ```
+   - For security:
+     - Store the key in a `.env` file using the `python-dotenv` package
+     - Never commit API keys to GitHub
+
+3. **Alternative APIs you can switch to**:
+   - [CurrencyFreaks](https://currencyfreaks.com/)
+   - [Open Exchange Rates](https://openexchangerates.org/)
+

 ## 🔐 API Access Notes
 
-This app currently uses the **[Frankfurter API](https://www.frankfurter.app/)**, which is free and does **not** require an API key.  
-If this changes in the future, follow these steps:
+This app currently uses the **[CurrencyFreaks API](https://www.currencyfreaks.com/)** 
+Follow these steps:
 
-1. **Check the official docs:** [frankfurter.app/docs](https://www.frankfurter.app/docs)  
-2. **If an API key is required**:
-   - Register for one on their website
-   - Update the API call in your code:
-     ```python
-     url = f"https://api.frankfurter.app/latest?amount={amount}&from={from_curr}&to={to_curr}&apikey=YOUR_API_KEY"
