$.getJSON('https://api.polygonscan.com/api?module=contract&action=getabi&address=0x0000000000000000000000000000000000001010&apikey=YourApiKeyToken', function (data) {
var contractABI = "";
contractABI = JSON.parse(data.result);
if (contractABI != ''){
var MyContract = web3.eth.contract(contractABI);
var myContractInstance = MyContract.at("0x0000000000000000000000000000000000001010");
var result = myContractInstance.memberId("0xfe8ad7dd2f564a877cc23feea6c0a9cc2e783715");
console.log("result1 : " + result);
var result = myContractInstance.members(1);
console.log("result2 : " + result);

Get Contract Source Code for Verified Contract Source Codes
1. https://api.polygonscan.com/api?module=contract&action=getsourcecode&address=0x0000000000000000000000000000000000001010&apikey=YourApiKeyToken (replace the address parameter with the actual contract address)
2. Terms of usage: Please see the usage terms policy
Verify Source Code (beta)
1. Requires a valid PolygonScan APIkey, will reject if otherwise
2. Current daily limit of 100 submissions per day per user (subject to change)
3. Only supports HTTP post due to max transfer size limitations for http get
4. Supports up to 10 different library pairs
5. Contracts that use "imports" will need to have the code concatenated into one file as we do not support "imports" in separate files. You can try using the Blockcat solidity-flattener or SolidityFlattery
6. List of supported solc versions, only solc version v0.4.11 and above is supported. Ex. v0.4.25+commit.59dbf8f1
7. Upon successful submission you will receive a GUID (50 characters) as a receipt.
8. You may use this GUID to track the status of your submission
9. Verified Source Codes will be displayed at contractsVerified

Logs APIs
The Event Log API was designed to provide an alternative to the native eth_getLogs. Below are the list of supported filter parameters:
- fromBlock, toBlock, address
- topic0, topic1, topic2, topic3 (32 Bytes per topic)
- topic0_1_opr (and|or between topic0 & topic1), topic1_2_opr (and|or between topic1 & topic2), topic2_3_opr (and|or between topic2 & topic3), topic0_2_opr (and|or between topic0 & topic2), topic0_3_opr (and|or between topic0 & topic3), topic1_3_opr (and|or between topic1 & topic3)
- FromBlock & ToBlock accepts the blocknumber (integer, NOT hex) or 'latest' (earliest & pending is NOT supported yet)
- Topic Operator (opr) choices are either 'and' or 'or' and are restricted to the above choices only
- FromBlock & ToBlock parameters are required
- An address and/or topic(X) parameters are required, when multiple topic(X) parameters are used the topicX_X_opr (and|or operator) is also required
- For performance & security considerations, only the first 1000 results are return. So please narrow down the filter parameters
Here are some examples of how this filter maybe used:
