FastAPI is a modern web framework first released in 2018 for building RESTful APIs in Python. [3] It is used for building APIs with Python 3.8+ based on standard Python-type hints.
FastAPI is based on Pydantic and uses type hints to validate, serialize and deserialize data. It also automatically generates OpenAPI documentation for APIs built with it. [4]
Pydantic is a data validation library for Python. While writing code in an IDE, Pydantic provides type hints for schema validation and serialization through type annotations. [5]
Starlette is a lightweight ASGI framework/toolkit, to support async functionality in Python. [6]
Uvicorn is a minimal low-level server/application web server for async frameworks, following the ASGI specification.
The following code shows a simple web application that displays " Hello World!" when visited:
from fastapi import FastAPI
app = FastAPI()
@app.get("/")
def read_root():
return "Hello World!"
