# Gas Station API

> Build powerful Solana applications with the Altude Gas Station API

## What is the Gas Station API?

The Altude Gas Station API is a powerful, developer-friendly REST API that simplifies Solana blockchain interactions. Instead of dealing with the complexity of raw blockchain transactions, our API provides clean, simple endpoints for account management and transaction processing.

### Key Features

* **Simplified Authentication**: Use API keys instead of complex wallet configurations
* **Account Management**: Create accounts, check balances, and view transaction history
* **Transaction Processing**: Send individual or batch transactions with ease
* **Multiple Token Support**: Work with USDC, KIN, and any Solana token
* **High Performance**: Optimized endpoints for fast, reliable blockchain interactions

### How to Use the API

The Gas Station API is designed to be intuitive and easy to integrate. All endpoints use standard REST principles with JSON request/response bodies. Authentication is handled via API keys in the X-API-Key header.

**Base URL**: `https://api.altude.so/api`

**Authentication**: `X-API-Key: YOUR_API_KEY`
