What potential pitfalls should be considered when connecting to external APIs for price comparison in PHP?

One potential pitfall when connecting to external APIs for price comparison in PHP is the lack of error handling, which can lead to unexpected behavior or crashes if the API request fails. To mitigate this, it is important to implement proper error handling to gracefully handle any errors that may occur during the API request. 

// Example of implementing error handling when connecting to an external API for price comparison

$url = 'https://api.example.com/prices';

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

if($response === false){
    // Handle the error gracefully
    echo 'Error occurred: ' . curl_error($ch);
} else {
    // Process the API response
    $data = json_decode($response, true);
    // Perform price comparison logic here
}

curl_close($ch);
