Echo Music now allows you to use your personal OpenRouter API key to translate song lyrics directly inside the app.

This guide explains how to get your API key, enter it into Echo Music, and understand your usage limits.

Why Echo Music Requires Your API Key

The lyrics translation feature uses AI models provided through OpenRouter.
By entering your own key, you benefit from:

• Full control over your translation limits
• Better reliability since you are not sharing quota with other users
• Access to free or paid usage depending on your preference
• Secure and private processing through your own OpenRouter account

Once the key is added to Echo Music, translations will work automatically.
