    let response = client
        .post("https://go.getblock.io/<ACCESS-TOKEN>/")
        .header("Content-Type", "application/json")

        }))
        .send()
        .await?;
    
    let result: serde_json::Value = response.json().await?;
    println!("{:#?}", result);

Web3 Integration

Ethers.js

import { ethers } from 'ethers';

const provider = new ethers.JsonRpcProvider('https://go.getblock.io/<ACCESS-TOKEN>/');

// Using ethers provider methods
const result = await provider.send('eth_getFilterLogs', ["0x1"]);
console.log(result);

Viem

import { createPublicClient, http } from 'viem';
import { sei } from 'viem/chains';

const client = createPublicClient({
    chain: sei,
    transport: http('https://go.getblock.io/<ACCESS-TOKEN>/')
});

// Using viem's request method
const result = await client.request({
    method: 'eth_getFilterLogs',
    params: ["0x1"]
});
console.log(result);
