Contract APIs

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.bscscan.com/api?module=contract&action=getabi&address=0x0000000000000000000000000000000000001004&apikey=YourApiKeyToken', function (data) {
    var contractABI = "";
        contractABI = JSON.parse(data.result);
        if (contractABI != ''){
            var MyContract = web3.eth.contract(contractABI);
            var myContractInstance = MyContract.at("0x0000000000000000000000000000000000001004");
            var result = myContractInstance.memberId("0xfe8ad7dd2f564a877cc23feea6c0a9cc2e783715");
            console.log("result1 : " + result);
            var result = myContractInstance.members(1);
            console.log("result2 : " + result);
        } else {
            console.log("Error" );
        }
    });
                                

Get Contract Source Code for Verified Contract Source Codes

                                    1. https://api-testnet.bscscan.com/api?module=contract&action=getsourcecode&address=0x0000000000000000000000000000000000001004&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 BscScan 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

Blocks APIs


Get Block Number by Timestamp

[Parameters] timestamp format: Unix timestamp (supports Unix timestamps in seconds), closest value: 'before' or 'after'

                                    https://api-testnet.bscscan.com/api?module=block&action=getblocknobytime&timestamp=1601510400&closest=before&apikey=YourApiKeyToken
                                

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:

Geth/Parity Proxy APIs


The following are the limited list of supported Proxied APIs for Geth available through BscScan.


eth_getBlockTransactionCountByNumber

Returns the number of transactions in a block from a block matching the given block number

                                    https://api-testnet.bscscan.com/api?module=proxy&action=eth_getBlockTransactionCountByNumber&tag=0x3d0900&apikey=YourApiKeyToken
                                

eth_getTransactionByBlockNumberAndIndex

Returns information about a transaction by block number and transaction index position

                                    https://api-testnet.bscscan.com/api?module=proxy&action=eth_getTransactionByBlockNumberAndIndex&tag=0x3d0900&index=0x0&apikey=YourApiKeyToken
                                

eth_sendRawTransaction

(Replace the hex value with your raw hex encoded transaction that you want to send.
Send as a POST request, if your hex code is particularly long)

eth_call

Executes a new message call immediately without creating a transaction on the block chain

                                    https://api-testnet.bscscan.com/api?module=proxy&action=eth_call&to=0xAEEF46DB4855E25702F8237E8f403FddcaF931C0&data=0x70a08231000000000000000000000000e16359506c028e51f16be38986ec5746251e9724&tag=latest&apikey=YourApiKeyToken
                                

(The gas parameter to eth_call is capped at 2x the current block gas limit)

eth_estimateGas

Makes a call or transaction, which won't be added to the blockchain and returns the used gas, which can be used for estimating the used gas

                                    https://api-testnet.bscscan.com/api?module=proxy&action=eth_estimateGas&data=0x4e71d92d&to=0xf0160428a8552ac9bb7e050d90eeade4ddd52843&value=0xff22&gasPrice=0x51da038cc&gas=0x5f5e0ff&apikey=YourApiKeyToken
