Ethereum: Binance API – Get Klines for XXX/GBP only

Code

// Set your API credentials and Binance Klines API endpoint
$url = '
$apiKey = YOUR_API_KEY_HERE; // Replace with your actual API key
$apiSecret = YOUR_API_SECRET_HERE; // Replace with your actual API secret
// Set the asset you want to retrieve prices for (in this case, BTC/ETH)
$asset = 'BTC/ETH';
// Define the time range you want to retrieve prices for (e.g., one day ago to today)
$startDate = '2023-02-20'; // Replace with the desired start date
$endDate = '2023-03-01'; // Replace with the desired end date
// Set the frequency of data retrieval (in this case, 1 minute intervals)
$frequency = '1m';
// Define any additional parameters you need (e.g. limit to fetch only one price per asset)
$params = array(
'symbol' => $asset,
'range' => $frequency,
'startTime' => $startDate,
'endTime' => $endDate
);
// Authenticate to the API using your credentials
$headers = array('Authorization: Binance-Key', 'Accept: application/json');
$ch = curl_init($url . '?' . http_build_query($params) . '&' . http_build_query(array('limit' => 100)));
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Execute the API call and retrieve the response
$response = curl_exec($ch);
$statusCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ($statusCode == 200) {
// Parse the JSON response to extract the data you need
$data = json_decode($response, true);
// Extract the price information for your asset of interest (BTC/ETH)
$priceData = array_filter($data[$asset]);
if (!empty($priceData)) {
echo "Current prices for $asset: ";
foreach ($priceData as $value) {

Explanation

This code snippet demonstrates how to use the Binance Klines API to retrieve the current prices of Bitcoin (BTC) and Ethereum (ETH). Here's a step-by-step breakdown:

• Define the asset for which you want to retrieve prices, in this case BTC/ETH.

• Specify the start date and end date for which you want to retrieve prices (e.g. 1 day ago to today).

• Set the data fetch frequency to 1 minute intervals.

• Define any additional parameters you need, such as limiting the number of price observations per asset.
