# API v1

## API key

An **API key** is a unique identifier linked to a user’s internal account. 

Issued by the **TRONEX** service, it allows users or third-party applications (such as bots or automated tools) to interact with the service directly—without using the Telegram bot.

Every API request, whether it’s checking a balance or creating a transaction order, is tied to the corresponding internal account through this key.

### How to use the API key

To authenticate, include your API key in the header of each request.

Header: **X-API-KEY**

Example:

```html
GET /api/v1/balance HTTP/1.1
Host: api.tronex.energy
X-API-KEY: YOUR_API_KEY
```

### Conclusion

An **internal account** serves as a secure space for storing and managing your assets, while an API key provides safe, automated access to that account.

For this reason, it’s essential to **keep your API key private and protect it from unauthorized use**.
