AKTools, the HTTP API interface of AKShare, is officially released this time, which can help users quickly build AKShare based HTTP APIs locally, so that users can break through the barriers of programming language and quickly obtain financial data.
AKTools
Introduction to AKTools
AKTools is a tool for quickly building HTTP API s. Through AKTools, you can start HTTP services through one line of code, so that the use of AKShare, an open-source financial data interface library originally dedicated to Python users, can break through the limitations of programming language. Whether you use C/C + +, Java, Go, Ruby, PHP, JavaScript and other programming languages, you can quickly and easily obtain financial data and help you better carry out research work.
AKTools Chinese document
Introduction to AKTools
AKShare is a Python library widely used in the open source financial data interface library. At present, it has been downloaded more than 20000000 times. Since its release, it has been actively maintained by the majority of data science lovers. The detailed and rich AKShare documents it provides greatly improve the efficiency of data search and use.
Introduction to FastAPI
As the most popular asynchronous Web framework in Python world, FastAPI is being loved by more and more data scientists and back-end programmers. This time, AKTools will combine AKShare and FastAPI to build a fast and efficient HTTP API tool.

Installation requirements
Because AKTools is based on AKShare and FastAPI, AKTools requires that your Python version is higher than Python 3.7(64 bit) and your operating system must be a 64 bit operating system. The detailed requirements shall be subject to the installation requirements of AKShare installation guide.
One click installation
pip install aktools # The installed version must be greater than 0.0.31
If the above methods cannot be upgraded to the latest version, please refer to the following methods for upgrading:

import aktools as at print(at.__version__)
quick start
This time, AKTools has been upgraded and simplified a lot, so that users can quickly and efficiently build HTTP API interface through one line of command to improve work efficiency.
Start from the command line
Open the command-line tool in the python environment that has been successfully installed and tested. If the cmd command-line tool for Windows, you only need to enter: python -m aktools to quickly start a local HTTP Server.
When the information shown in the above figure is displayed on your console, you can open your browser. Take Chrome browser as an example, you only need to enter in the address bar: http://127.0.0.1:8080/api/stock_zh_a_hist Get data quickly.
Specify parameter settings
You can specify the host and port number of HTTP Server: python -m aktools --host 0.0.0.0 --port 8888. You can set the host and port through -- host and -- port.
When the information shown in the above figure is displayed on your console, you can open Postman as an example. You only need to enter in the request column: http://0.0.0.0:8888/api/stock_zh_a_daily Get data quickly.
