A simple sample for retrieving the contractABI using Web3.js and Jquery to interact with a contract.

var Web3 = require('web3');
var web3 = new Web3(new Web3.providers.HttpProvider());
var version = web3.version.api;
        
$.getJSON('https://api.mantlescan.xyz/api?module=contract&action=getabi&address=0xfb6916095ca1df60bb79ce92ce3ea74c37c5d359', function (data) {
    var contractABI = "";
    contractABI = JSON.parse(data.result);
    if (contractABI != ''){
        var MyContract = web3.eth.contract(contractABI);
        var myContractInstance = MyContract.at("0xfb6916095ca1df60bb79ce92ce3ea74c37c5d359");

Verify Source Code

Submits a contract source code to Mantlescan for verification.

📝 Note : This endpoint is limited to 100 verifications/day, regardless of API PRO tier.

1. Requires a valid Mantlescan API key, it will be rejected otherwise

2. Only supports HTTP POST due to max transfer size limitations for HTTP GET

3. Supports up to 10 different library pairs

4. Contracts that use "imports" will need to have the code concatenated into one file as we do not support "imports" in separate files.

5. List of supported solc versions, only solc version v0.4.11 and above is supported e.g. v0.4.25+commit.59dbf8f1

6. Upon successful submission you will receive a GUID (50 characters) as a receipt

7. You may use this GUID to track the status of your submission

8. Verified Source Codes will be displayed at the Verified Contracts page.

Check Source Code Verification Submission Status

👇 Note: Upon successful submission, a GUID is returned, which can be used to check for submission status.

//Check Source Code Verification Status
$.ajax({
    type: "GET",
    url: "//api.etherscan.io/api",
    data: {
        apikey: $('#apikey').val(), 
        guid: 'ezq878u486pzijkvvmerl6a9mzwhv6sefgvqi5tkwceejc7tvn', //Replace with your Source Code GUID receipt above

        action: "checkverifystatus"
    },
    success: function (result) {
        console.log("status : " + result.status);   //0=Error, 1=Pass 
        console.log("message : " + result.message); //OK, NOTOK
        console.log("result : " + result.result);   //result explanation
