I am new to blockchain development and i am trying to get detail data of a contract like (marketcap, holders, amount...) from the Binance Smart Chain (BSC), and i am trying to use the BSC Scan API (https://bscscan.com/apis#contracts) and i also see another options like Bit query (https://bitquery.io/blog/ethereum-events-api) which one should i use, Thank you in advance.

An official API is available for getting ABI versions of bscscan.com verified contracts.
This is a sample call from browser:
https://api.bscscan.com/api
?module=contract
&action=getabi
&address=0x0e09fabb73bd3ade0a17ecc321fd13a19e81ce82
&apikey=YourApiKeyToken
The Javascript sample:
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");
}
});
