Ethereum Klines API: Get Current Bitcoin/ETH Prices

The Binance Klines API is a powerful tool for analyzing market data, so in this article we will explore how to use it to get current Bitcoin (BTC) and Ethereum (ETH) prices.

Prerequisites

Before you begin, make sure you have the following:

• Binance API account

• Binance Klines API endpoint (

Code

// Set 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 get prices for (in this case BTC/ETH)
$asset = 'BTC/ETH';
// Set the time interval you want to get prices for (e.g. from 1 day 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 may need (e.g. limit to only get one price per asset)
$params = array(
'symbol' => $asset,
'interval' => $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_RETURNNTTRANSFER, true);
// Execute the API call and get the response
$response = curl_exec($ch);
$statusCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ($statusCode == 200) {
// Parse the JSON response to get the required data
$data = json_decode($response, true);
// Extract the price information of the asset of interest (BTC/ETH)
$pricedata = array_filter($data[$asset]);
if (!empty($priceData)) {
echo "Current prices of $asset: ";
foreach ($priceData as $value) {
echo "$value[1] ($value[2])\n";
}
} else {
echo "Data $asset\n not found";
}
} else {
echo "Error reading data ($statusCode)\n";
}
?>

Explanation

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

• Set the API credentials (“apiKey” and “apiSecret”) as environment variables or in a file.

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

• Specify the start and end dates you want to retrieve prices for (e.g., from 1 day to today).

• Set the data retrieval frequency to 1-minute intervals.

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

Note

: This code snippet assumes that the Binance API supports retrieving multiple assets and time frames at once. If not, you will need to modify the “params” array accordingly.

Following these steps should get you the current prices for the asset you want using the Binance Klines API.
