Trying to get an api request getting error 404

Question

I'm trying to get a list of locations from a website called weedmaps. This is the code that I'm using:

function call_for_api() {


    $url='https://api-v2.weedmaps.com/api/v2/listings';
    $response = wp_remote_post( $url, array(
        'timeout' => 45,
        'redirection' => 5,
        'httpversion' => '1.0',
        'blocking' => true,
        'headers' => array('accept'=>'application/json','accept-encoding' => 'gzip, deflate, br','connection' =>'keep-alive'),
        'body' => null,
        'cookies' => array(),
        'compress'    => false,
            'decompress'  => true,
            'sslverify'   => true,
            'stream'      => false,
            'filename'    => null,  
        'user-agent' => 'Mozilla/5.0 (Windows NT 10.0; WOW64; rv:54.0) Gecko/20100101 Firefox/54.0'
                )
        );

    if ( is_wp_error( $response ) ) {
         $error_message = $response->get_error_message();
        echo "Something went wrong: $error_message";
    } else {
         echo 'Response:<pre>';
         print_r( $response );
             echo '</pre>'; 
 echo wp_remote_retrieve_body( $response );

    }
}

function cf_shortcode() {
    ob_start();
    call_for_api();

    return ob_get_clean();
}

add_shortcode( 'weed-list', 'cf_shortcode' );

When I'm viewing the maps page on weedmaps . com and view my network tab this appears to be the right endpoint. I think I've missed something in how the wp_remote_post works.

I've never seen a 404 on api, but I'm a bit new to that.

It looks like I did the call right, but maybe the api experts see what I did wrong here.

This is the error message I get:

    [headers] => Requests_Utility_CaseInsensitiveDictionary Object

        )

Try using a GET request instead of a POST request. The headers indicate they only allow origin from weedmaps.com in the POST request. The method in WordPress is wp_remote_get().

    function call_for_api() {
        $url='https://api-v2.weedmaps.com/api/v2/listings';
        $response = wp_remote_get( $url,
            array(
                'timeout'     => 45,
                'redirection' => 5,
                'httpversion' => '1.0',
                'blocking'    => true,
                'headers'     => array(
                    'accept'          => 'application/json',
                    'accept-encoding' => 'gzip, deflate, br',
                    'connection'      =>'keep-alive'
                ),
                'body' => null,
                'cookies'     => array(),
                'compress'    => false,
                'decompress'  => true,
                'sslverify'   => true,
                'stream'      => false,
                'filename'    => null,  
                'user-agent'  => 'Mozilla/5.0 (Windows NT 10.0; WOW64; rv:54.0) Gecko/20100101 Firefox/54.0',
            )
        );

        if ( is_wp_error( $response ) ) {
            $error_message = $response->get_error_message();
            echo "Something went wrong: $error_message";
        } else {
            echo 'Response:<pre>';
            print_r( $response );
            echo '</pre>'; 
            echo wp_remote_retrieve_body( $response );
        }
}

function cf_shortcode() {
    ob_start();
    call_for_api();

    return ob_get_clean();
}

add_shortcode( 'weed-list', 'cf_shortcode' );
