Web Development With Fastapi Development Tutorials, Guides & Insights

Let’s create an API endpoint where users can submit text, and the app will return the sentiment of that text using the AI model.

   from fastapi import FastAPI
   from pydantic import BaseModel

   app = FastAPI()

   # Define request body
   class TextInput(BaseModel):
       text: str

   # Endpoint for sentiment analysis
   @app.post("/analyze/")
   def analyze_text(input: TextInput):
       result = sentiment_analysis(input.text)
       return {"text": input.text, "sentiment": result[0]}
