Create a Go file called main.go:

package main

import (
	"bytes"
	"encoding/json"
	"fmt"
	"io"
	"net/http"
)

const url = "https://rpc.testnet.tryradi.us/<YOUR-RPC-ENDPOINT>"

func main() {
	payload := map[string]interface{}{
		"jsonrpc": "2.0",
		"method":  "eth_blockNumber",
		"params":  []string{},
		"id":      1,
	}

	jsonPayload, err := json.Marshal(payload)
	if err != nil {
		fmt.Println("Error marshalling JSON:", err)
		return
	}

	resp, err := http.Post(url, "application/json", bytes.NewBuffer(jsonPayload))
	if err != nil {
		fmt.Println("Error sending request:", err)
		return
	}
	defer func(Body io.ReadCloser) {
		err = Body.Close()
		if err != nil {

		}
	}(resp.Body)

	body, err := io.ReadAll(resp.Body)
	if err != nil {
		fmt.Println("Error reading response:", err)
		return
	}

	var result map[string]interface{}
	err = json.Unmarshal(body, &result)
	if err != nil {
		fmt.Println("Error parsing JSON response:", err)
		return
	}

	fmt.Println(result)
}
