## **Getting Started with dRPC API**

### Sign Up and Get an API Key

- Create an account on [dRPC website](https://drpc.org).
- Generate your API key from the dashboard.

### Configure Your Endpoint

Use the base URL for the desired blockchain network:

- **Ethereum Mainnet:**

```
https://eth-mainnet.drpc.org/YOUR_API_KEY
```

- **Binance Smart Chain Testnet:**

```
https://bsc-testnet.drpc.org/YOUR_API_KEY
```

### Example API Call

Here’s a sample request to fetch the latest block number on Ethereum:

```json
{
  "jsonrpc": "2.0",
  "method": "eth_blockNumber",
  "params": [],
  "id": 1
}
```

## **Make Your First Call**

### Open an API client like Postman or curl

This will enable you test your API

### Use the Ethereum Mainnet endpoint as an example: 

```bash
https://eth-mainnet.drpc.org/YOUR_API_KEY
```

### Send the following JSON-RPC request:

```json
{
 "jsonrpc": "2.0",
 "method": "eth_getBalance",
 "params": ["0xYourEthereumAddress", "latest"],
 "id": 1
}
```

### You’ll receive a response like this:

```json
{
"jsonrpc": "2.0",
"result": "0x0234c8a3397aab58",
"id": 1
}
```

The `result` field contains the balance in Wei (smallest Ether unit).

## **Advanced Features**

### Batch Requests

Efficiently send multiple queries in a single request:

```json
[
  { "jsonrpc": "2.0", "method": "eth_blockNumber", "params": [], "id": 1 },
  { "jsonrpc": "2.0", "method": "eth_getBalance", "params": ["0xYourAddress", "latest"], "id": 2 }
]
```

### WebSocket Subscriptions

Subscribe to live events like new blocks or logs:

```json
{
  "jsonrpc": "2.0",
  "method": "eth_subscribe",
  "params": ["newHeads"],
  "id": 1
}
```

### REST Endpoints

For developers preferring REST over JSON-RPC, dRPC offers RESTful APIs for common operations:

```
GET https://eth-mainnet.drpc.org/v1/account/0xYourEthereumAddress/balance
```
