Features

1. Health Check Endpoint

• Endpoint: /health
• Method: GET
• Description: Verifies that the API is running and operational.
• Request Body: None

2. Question Answering Endpoint

• Endpoint: /answer

• Method: POST

• Description: Takes a user question and context, processes it using a pre-trained AI model, and returns the answer with a confidence score. This endpoint originally used the distilbert-base-uncased-distilled-squad model, which gave a confidence level of 0.52. To improve performance, we switched to the bert-large-uncased-whole-word-masking-finetuned-squad model, increasing the confidence level to 0.72 for the same input.

• Request Body:

  {
      "question": "What are the store hours?",
      "context": "Our store is open from 9 AM to 9 PM every day."
  }
  

• Response:

  {
    "question": "What are the store hours?",
    "answer": "9 AM to 9 PM",
    "confidence": 0.73
  }
