I want to use Blockchain receive API without exchange rate

Question

I have integrated Blockchain recieve API for a Blockchain Payment Gateway but when I try to enter an amount to add balance it converts that amount into USD. How do I get it in BTC?

Trying to remove the below URL from my code but not helping:

if ($sendto!="") {
                $api = "https://blockchain.info/tobtc?currency=USD&value=".$data['amount'];

                $usd = file_get_contents($api );
                $tran->btc_amo = $usd;
                $tran->btc_acc = $sendto;
                $tran->save();

Answer 1

You are not using receive API you are using Exchange Rates API which  needs currency and

If you need USD to BTC, you can try this:

$one_usd_in_btc = https://blockchain.info/tobtc?currency=USD&value=1
$usd_to_btc     = $one_usd_in_btc * your_usd
