Ethereum: Query paginated API endpoint from end to the very first item by providing start and endtime parameters
Request Ethereum historical data using the paginated API endpoint
I see that you are having trouble getting data from the API of Binance, a popular trading and data storage platform. Specifically, you want to query historical Ethereum data using a paginated endpoint.
The problem you’re experiencing may be related to how the Binance API handles pagination, or to limitations in the API documentation. Here is an article that provides recommendations for achieving this goal:
Introduction
Historical data is necessary to analyze and make informed decisions about cryptocurrencies such as Ethereum. The Binance API offers a paginated endpoint for historical data, allowing you to extract all available data for each period.
Step 1. Define the End-to-First Item (E2I) Request Template
To request an E2I template, we need to understand how the Binance API handles pagination. A common approach is to use the from' andto’ parameters to specify the start and end timestamps for the data.
For example, suppose you want to retrieve all historical Ethereum transactions from January 1, 2020 to January 31, 2022. You can use this request:
{
"method": "GET",
"url": "
"params": {
"ids": [],
"fields": [
"open",
"high",
"low",
"close",
volume
]
}
}
Step 2: Analysis and processing of the response
After receiving the response, analyze it to extract relevant data. The klines endpoint returns an array of objects with different fields for each transaction.
For example:
[
{
"id": 0,
"timestamp": 1643723400,
"open": 10000000,
"high": 15000000,
"low": 9000000,
"close": 10500000,
"volume": 5000
},
{
"id": 1,
"timestamp": 1643723405,
"open": 10200000,
"high": 12000000,
"low": 9200000,
"close": 10800000,
"volume": 6000
},
...
]
Step 3: Implement Pagination
To to implement pagination, you need to add the limit parameter to your request. The limit value depends on the number of elements returned on the page.
For example:
{
"method": "GET",
"url": "
"params": {
"ids": [],
"fields": [
"open",
"high",
"low",
"close",
volume
]
}
}
Conclusion
Extracting all available historical Ethereum data requires some work, but with the right approach you can achieve your goal. By following these steps and understanding how to implement pagination using the Binance API, you will be able to successfully request an E2I template.
