Querying Binance Historical Data API with Specific Time and Date
Yes, that’s correct. The binance API provides historical data for various cryptocurrencies, including Ethereum (ETH). However, the query you want to make is a bit unconventional – you’re looking to retrieve the price of a specific cryptocurrency at a specific time in the past using historical data.
Is this kind of querying possible?
While Binance’s historical data API does allow you to access historical prices for various cryptocurrencies and time intervals (e.g., daily, weekly), it doesn’t directly support retrieving prices at specific times. The API returns price data for a set time interval, but not necessarily for a specific date or time.
How can we achieve this?
To query the binance API with a specific time and date, you’ll need to use a programming language that supports querying APIs using APIs. In this case, I recommend using Python due to its ease of use and extensive libraries.
Here’s an example code snippet to get you started:
import requests
Set your Binance API credentials
api_key = 'your_api_key'
api_secret = 'your_api_secret'
Set the specific cryptocurrency and time interval (e.g., ETH-1h)
cryptocurrency = 'eth'
time_interval = '1h'
1 hour ago to today
Construct the API request URL
url = f' historical candlestick/ETH/{time_interval}'
Set your Binance API endpoint and headers (optional)
headers = {
'Authorization': f'Bearer {api_key}',
'Content-Type': 'application/json'
}
Send the GET request
response = requests.get(url, headers=headers)
Check if the response was successful
if response.status_code == 200:
Parse the JSON data
data = response.json()
Extract the price (ETH-1h) from the data
prices = data['candles']
for candle in prices:
if candle['symbol'] == cryptocurrency and candle['time'].split(' ')[0] == '1103':
print(f'Price of {cryptocurrency} at 1103 hours Friday, 31 August 2018: ${candle["close"]}')
else:
print(f'Failed to retrieve data. Status code: {response.status_code}')
How it works
- We construct the API request URL using the
ethcryptocurrency and a time interval of1h.
- We set our Binance API credentials, including an API key and secret.
- We send the GET request to the API endpoint with the specified headers (optional).
- If the response is successful, we parse the JSON data from the response body.
- We iterate through the candlestick prices for the
ethcryptocurrency and check if a specific price matches our target time interval (1103 hours Friday, 31 August 2018).
Note that this code snippet assumes you have the necessary dependencies installed (e.g., requests, json library). You may need to modify the API endpoint and headers as needed for your specific use case.
Additional considerations
- Make sure to handle errors properly, such as checking if the response was successful or parsing JSON data correctly.
- Consider implementing error handling measures to mitigate potential issues with the API request.
- This code snippet is just a starting point. You may need to adjust it to suit your specific requirements and modify the time interval or cryptocurrency accordingly.
