Interact with RPC, REST, and gRPC endpoints across 80+ blockchains using ready-to-run examples in JavaScript, Python, Go, and more. Use Quicknode products like Streams, Webhooks, and IPFS to build and run blockchain applications from one platform.

## Send Your First Request

Make a JSON-RPC call to get the latest block number on Ethereum:

```bash
curl https://docs-demo.quiknode.pro/ \
  -X POST \
  -H "Content-Type: application/json" \
  --data '{"method":"eth_blockNumber","params":[],"id":1,"jsonrpc":"2.0"}'
```

```javascript
const response = await fetch('https://docs-demo.quiknode.pro/', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    method: 'eth_blockNumber',
    params: [],
    id: 1,
    jsonrpc: '2.0',
  }),
});
const data = await response.json();
console.log(data.result);
```

```python
import requests

url = "https://docs-demo.quiknode.pro/"
payload = {"method": "eth_blockNumber", "params": [], "id": 1, "jsonrpc": "2.0"}
response = requests.post(url, json=payload)
print(response.json()["result"])
```
