api-autogen 0.1.0

A simple decorator to convert Python functions into FastAPI endpoints

API AutoGen

Overview

API AutoGen is a Python package that provides a simple way to convert functions into FastAPI endpoints using a decorator.

Installation

To install the package, run:

pip install git+https://github.com/lechplace/api_autogen.git

Example Usage

1. Creating API Endpoints with the @api_func Decorator

Define your functions and use the @api_func decorator to automatically expose them as API endpoints.

Example:

from api_autogen import api_func, app
from pydantic import BaseModel

@api_func("math_funcs")
def add(a: int, b: int) -> int:
    return a + b

class MultiplyInput(BaseModel):
    a: int
    b: int

@api_func("math_funcs")
def multiply(data: MultiplyInput) -> int:
    return data.a * data.b

2. Where the Decorator is Used

• The @api_func("math_funcs") decorator is applied to functions (add and multiply).
• It registers these functions as API endpoints under the path /math_funcs/add and /math_funcs/multiply.

3. Where the FastAPI App is Defined

• The FastAPI application instance app is provided in api_autogen and should be used in the main application script.

4. Running the API Server

Start the FastAPI application using Uvicorn:

uvicorn api_autogen:app --reload

• The server will start at http://127.0.0.1:8000.
• Navigate to http://127.0.0.1:8000/docs to explore the auto-generated API documentation.
