FastAPI - Authentication and Security

Identify the error in this FastAPI security code snippet:

from fastapi import FastAPI, Security
from fastapi.security import APIKeyHeader

app = FastAPI()
api_key_header = APIKeyHeader(name="Authorization")

@app.get("/secure")
async def secure_route(api_key: str = Depends(api_key_header)):
    return {"key": api_key}

AFunction should not be async

BMissing import of Depends

CAPIKeyHeader name should be "X-API-Key"

DUsing Depends instead of Security for APIKeyHeader dependency

Step-by-Step Solution

Solution:

Step 1: Check for import errors
The code uses 'Depends(api_key_header)' but 'Depends' is not imported. Only FastAPI and Security are imported from fastapi.
Step 2: Confirm dependency usage is otherwise correct
Using Depends with APIKeyHeader is valid; adding 'from fastapi import Depends' would fix it. Header name and async are fine.
Final Answer:
Missing import of Depends -> Option B
Quick Check:
Missing Depends import causes NameError [OK]

Quick Trick: Always import Depends for FastAPI dependencies [OK]

Common Mistakes:

MISTAKES

Confusing Depends and Security usage
Thinking header name must be fixed
Believing async is not allowed
