Open-source solutions for exposing Python as an API endpoint

FastAPI is a modern, fast (high-performance) web framework for building APIs with Python 3.7+ based on standard Python-type hints. It’s easy to use and allows you to create robust APIs quickly.

You can install FastAPI using pip:

pip install fastapi

The following is a simplified example of creating a FastAPI endpoint to expose a Python function:

from fastapi import FastAPI, Query
app = FastAPI()
@app.get("/api/add")
def add_numbers(
    num1: int = Query(..., description="First number"),
    num2: int = Query(..., description="Second number"),
):
    result = num1 + num2
    return {"result": result}

In this example, the add_numbers function available at the /api/add endpoint takes two query parameters (num1 and num2), representing the numbers to be added. The Query function from FastAPI...
