Hi, i just want to make my own api with piklist fields, is there any way to make this?

i just have a piklist field

//horarios
$days = array();

$days[0] = “Choose an option”;
$days[1] = “Monday”;
$days[2] = “Tuesday”;
$days[3] = “Wednesday”;
$days[4] = “Thursday”;
$days[5] = “Friday”;
$days[6] = “Saturday”;
$days[7] = “Sunday”;

piklist(‘field’, array(
‘type’ => ‘group’
,’columns’ => 12
,’label’ => __(‘Horarios de la parroquia’)
,’field’ => ‘parroquia_horarios’
,’add_more’ => true
,’fields’ => array(
array(
‘type’ => ‘select’
,’field’ => ‘day’
,’columns’ => 6
,’attributes’ => array(
‘class’ => ‘text’
),
‘choices’ => $days,
‘required’ => true
)
,array(
‘type’ => ‘text’
,’field’ => ‘time’
,’columns’ => 6
,’attributes’ => array(
‘placeholder’ => ’09:00′
)
)
)

));

i want to request my endpoint and receive by answer something like this

{
“Monday” : [
“00:09″,”12:00″,”15:00”, …and so on
],
“Thursday” : [
…
]
}
