Ethereum: Query the page API endpoint to reach the first goal, providing start and end time parameters
Querying Ethereum Historical Data with a Paginated API Endpoint
I see that you are having trouble retrieving data from the Binance API, which is a popular platform for trading and storing data. Specifically, you want to query Ethereum historical data using a paginated endpoint.
The issue you are experiencing may be due to the way the Binance API handles pagination or limitations in its API documentation. Here is an article that provides guidance on how to accomplish this:
Introduction
Historical data is essential for analyzing and making informed decisions about cryptocurrencies like Ethereum. The Binance API provides a paginated endpoint for retrieving historical data, allowing you to retrieve all available data for each period.
Step 1: Identify the End-to-First-Item (E2I) Query Pattern
To query the E2I pattern, we need to understand how the Binance API handles pagination. The general approach is to use the from and to parameters to specify the start and end timestamps for the data.
For example, let’s say you want to retrieve all historical Ethereum transactions from January 1, 2020 to January 31, 2022. You can use a query like this:
{
"method": "GET",
"url": "
"params": {
"ids": [],
"fields": [
"open",
"high",
"low",
"close",
"volume"
]
}
}
Step 2: Parse and process the response
Once you receive the response, parse it to extract the relevant data. The “lines” 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 implement pagination, you need to add the limit parameter to your query. The limit value depends on the number of items returned per page.
For example:
{
"method": "GET",
"url": "
"params": {
"ids": [],
"fields": [
"open",
"high",
"low",
"close",
"volume"
]
}
}
Conclusion
Retrieving all available Ethereum historical data takes a bit of 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 should be able to successfully query the E2I model.
