ByBit API returns error: Param validation for 'symbol' failed on the 'linear_symbol' tag

[kadnan]

I am trying to fetch the BTCUSD data but it returns the following:

(
    [ret_code] => 10001
    [ret_msg] => Param validation for 'symbol' failed on the 'linear_symbol' tag
    [ext_code] => 
    [ext_info] => 
    [result] => 
    [time_now] => 1612508984.802319
    [token] => 
)

The code I am using is:

$bybit = new BybitLinear();
$pair = 'BTCUSD';
$interbal_in_action = '1d';
$result = $bybit->publics()->getKline( [
            'symbol'   => $pair,
            'interval' => $interval_in_action,
            'limit'    => 10,
            'from'     => $from,
        ] );
        print_r($result);

Update

It seems that BybitAPI Does support for BTCUSD but in Inverse but your API does not support it

Thank you for your discovery, let me first see how to solve it

You try this

$bybit=new BybitInverse();
try {
    $result=$bybit->publics()->getKlineList([
        'symbol'=>'BTCUSD',
        'interval'=>'15',
        'from'=>time()-3600,
    ]);
    print_r($result);
}catch (\Exception $e){
    print_r($e->getMessage());
}
