Title: Can’t Get Information From Binance API with JSON: A Guide To Understanding API Limitations and Workarounds

Introduction

As a developer, get the information you need is one of the most exciting aspects of working on projects. However, when it comes to apis like the Binance API, understanding their limitations can be challenging. In this article, we’ll explore why retrieving data from the Binance API with json might not work out and provide some workarounds.

why can’t I get the information from the URL API with JSON?

The Binance API is a restful API that provides access to various financial market, including cryptocurrency prices. When you send a get request to a specific url using the Requests Library in python, it sends an http request to the server and receives a response. The Response contains the requested data, but json (JavaScript object note) is not typically used with restful apis.

The main issue here is that the Binance Api does not use json by default. Instead, it returns the date as plain text in the form of a string. This is because restful apis often don’t need to support json for their internal data exchange; Instead, they provide a simple and convenient way to access their resources.

why doesn’t my url work with json?

When you send a get request to https: // api.binance.com/API/V1/Ticker/24hr, the server responds with a plain text string containing the ticker list for 24-hour prices. This string is not formatted in a way that can be easily parsed into a python divionary or object.

HERE’S What the Response Might Look Like:

`JSon

[

{

"Symbol": "BTC/EUR",

"lastprice": "4.0025",

"High": "4.0065",

"Low": "3.9930",

"Open": "4.0011",

"Close": "4.0032"

},

{

"Symbol": "ETH/USD",

"Lastprice": "4.0027"

}

]

This response does not contain a json object, but buy a list of divested data.

Workarounds:

If you need to retrieve data from the Binance API with JSON, here are some workarounds:

  • Use the Json Parameter : You can specify theJson Parameter When Making the Get Request:

`python

Import Requests

Binance = Requests.get (" JSON = True)

This will return a json object containing the ticker list.

  • Use the Data Attribute : You can also access the Response Data Using the Data Attribute:

`python

Import Requests

Binance = Requests.get ("

Print (Binance.json ())

This will print out a JSON Object containing the Requested Data.

  • use a library like Requests-json-parser: there are libraries available that can parse json responses into python objects, such as Requests-json-parser:

python

Import Requests

from requests_json_parson import parse_json_response

Binance = Requests.get ("

parsed_data = parse_json_response (Binance.text)

Print (parsed_data)

These workarounds may have limitations or requirement additional setup, but they can help you overcome the issue of retrieving data from a URL API with JSON.

Conclusion

In summary, the Binance API does not use json by default, and its response format is plain text. To retrieve data from the API using python, you need to specify the json parameter or access the response data using other methods like parsing json or loading into a python object. While it may require additional setup or library usage, these workarounds can help you overcome common issues when working with apis that they don’t support json out of the box.
