PHP Code to Fetch PEPE coin pricing based in USD from Coinbase

To fetch the current pricing for a cryptocurrency like PEPE using the Coinbase API with PHP and cURL, follow this guide:

Prerequisites:

• Ensure you have access to the Coinbase Exchange Rates API, which doesn't require authentication for public endpoints.

Example Code for PEPE Pricing

<?php
// Define the API endpoint
$currency = 'PEPE'; // Replace with the symbol of the cryptocurrency
$baseCurrency = 'USD'; // Replace with the desired fiat or base currency
$endpoint = "https://api.coinbase.com/v2/prices/{$currency}-{$baseCurrency}/spot";

// Initialize cURL
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $endpoint);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute the request
$response = curl_exec($ch);

// Check for errors
if (curl_errno($ch)) {
    echo 'cURL error: ' . curl_error($ch);
} else {
    // Parse and display the response
    $data = json_decode($response, true);

    if (isset($data['data']['amount'])) {
        echo "The current price of {$currency} in {$baseCurrency} is: " . $data['data']['amount'];
    } else {
        echo "Failed to retrieve price. Response: " . $response;
    }
}

// Close cURL
curl_close($ch);
?>

Explanation:

1. Endpoint: The Coinbase /v2/prices/{currency}-{base_currency}/spot endpoint provides the current spot price for a cryptocurrency.
2. Example:
   • Replace PEPE with the desired cryptocurrency code.
   • Replace USD with the base currency in which you want the price.

Output:

• If successful: The current price of PEPE in the specified currency.
• If the cryptocurrency isn't available, the API response will indicate the issue.
