Single API call except multiple calls

Question

Sorry for stupid question, but maybe someone could help me. I need to make an API call to bscscan with ~150 contractAddreses which I have in one array, but due to bscscan limit of 5 calls/sec can't do it. So I have a question if I can shoot just with one API call with all contractAddresses except multiple calls. Are there any possibilities? I have an array:

let contractAddrs = ['contractAddress1', 'contractAddress1', 'contractAddress1',...., 'contractAddress150']

That's how API endpoint looks like

https://api.bscscan.com/api?module=stats&action=tokenCsupply&contractaddress=CONTRACTADDRESSHERE&apikey=YourApiKeyToken

So how can I put all those contractAddrs to API call and shoot once?

Thanks ^^

I don't think they have an endpoint for bulk request for addresses but you can do something like this.

const addressArr = [
// ...
];

const promise = new Promise((res, rej) => {
    let i = 0;
    const resolved = []
    setInterval(() => {
        // ... make your api request and push to resolved
        i++;
        if (i >= addressArr.length) {
            res(resolved);
        }
    }, 300)
})

// ... do something when the request are done
