# API Security Best Practices

To ensure secure and reliable usage of the Scanurl.ai API, follow these guidelines:

### Protect Your API Key

* Never expose your API key in frontend applications
* Always store and use it from a secure backend or server
* Do not commit API keys to public repositories

### Use Secure Storage

* Store API keys in environment variables or secure vaults
* Avoid hardcoding keys in source code

### Rotate API Keys

* Periodically rotate your API keys
* Immediately regenerate if a key is exposed or compromised

### Control API Usage

* Respect your plan’s rate limits (RPS)
* Avoid sending unnecessary or duplicate requests
* Implement request throttling on your side if needed

### Handle Failures Properly

* Implement retry logic with delays
* Do not continuously retry failed requests without control

### Use Secure Connections

* Always call the API over HTTPS
* Do not use unsecured or modified endpoints
