Here is an article that explains how to programmatically retrieve historical Ethereum transactions for a specific period (last 10 days) from Bittrex using their API:
Getting Ethereum Transaction History from Bittrex API: Step-by-Step Guide
Introduction
————-
Bittrex is a popular cryptocurrency exchange that allows users to buy, sell, and trade various cryptocurrencies. One of the key features of the Bittrex API is the ability to retrieve historical market data for any period, including transactions. In this article, we will explain how to retrieve Ethereum transaction history from Bittrex using their API.
Prerequisites
Before you begin, make sure you have:
- A Bittrex account and are logged in.
- Bittrex API credentials (API key, API secret, etc.)
- Your programming language of choice (e.g. Python, JavaScript)
Step 1: Install the required libraries
In this example, we will use the 'requests' library to make HTTP requests to the Bittrex API. You can install it using pip:
"bash
pip install requests
Step 2: Authenticate with Bittrex
To authenticate with Bittrex, you must provide your API key and secret in the request headers or as a request parameter.
python
import json
Replace with your actual API credentials
api_key = 'YOUR_API_KEY'
api_secret = 'YOUR_API_SECRET'
headers = {
'x-apikey': api_key,
'x-apisecret': api_secret
}
query_params = {
'market': 'eth',
Set the market to Ethereum (ETH)
'limits': 100,
Limit the number of transactions to download
'datetime': 'YYYY-MM-DDTHHMMSSUTC'
Specify the start and end dates/time ranges
}
Step 3: Get Historical Transactions
Now that you are authenticated with Bittrex, you can use the 'queries' library to make a GET request to the API. We will specify the query parameters we provided earlier.
python
import requests
def get_history_trades(api_key, api_secret, market, limit, datetime_start, datetime_end):
url = ' + market + '/history'
params = {
'limit': limit,
'datetime_start': datetime_start,
'datetime_end': datetime_end
}
response = requests.get(url, headers=headers, params=params)
if response.status_code = = 200:
data = response.json()
trade = []
for trade data [trade]:
Extract the relevant fields from the trade object
transaction_id = trade['id']
timestamp = trade['timestamp']
price = trade['amount']
amount = trade['amount']
trades.append({
'transaction_id': transaction_id,
'timestamp': timestamp,
'price': price,
'amount': amount
})
return trades
else:
print(f'Error: {response.status_code}')
return None
Usage Example
api_key = 'YOUR_API_KEY'
api_secret = 'YOUR_API_SECRET'
market = 'eth'
limit = 100
datetime_start = '2023-02-20T00:00:00Z'
datetime_end = '2023-03-07T00:00:00Z'
trades = get_history_trades(api_key, api_secret, market, limit, datetime_start, datetime_end)
if trade:
for trade in trade:
print(f'Trade ID: {trade["transaction_id"]}')
print(f'Timestamp: {trade["timestamp"]}')
print(f'Price: ${trade["price"]} ({trade["amount"]} ETH)')
print ('——————-')
else:
print ("No historical transactions found.")

Troubleshooting
- Check the Bittrex API documentation for any possible changes to query parameters or endpoints.
- Make sure you have the correct API credentials and are using them correctly.
- If you are having issues with authentication or data retrieval, check the Bittrex API logs for error messages.
