Update api.php

Browse source 
Error Handling: Check for cURL errors and handle them gracefully.
Array Creation: Used [] instead of array() and simplified array creation.
Null Coalescing Operator: Used ?? for safer access to possibly undefined properties.
Function Isolation: Split the cURL preparation and search logic into separate functions for clarity.
Consistent Naming: Renamed prepare_search_curl_obj to prepareSearchCurlObj for consistency in naming conventions.
