from fastapi import FastAPI

app = FastAPI()

@app.get("/items/")
async def read_item(q: str):
    return {"q": q}

1. Use the @app.get decorator to create a route that will receive the query parameters.
2. Define the query parameter within the route function. In the example above, we are expecting a query parameter named q.
3. You can then access the query parameter within the function and process it as needed. In the example above, we are simply returning the query parameter as part of a dictionary.
4. You can test this route by making a GET request to http://localhost:8000/items/?q=your_query_parameter using a tool like Postman or curl.

By following these steps, you can process a query using FastAPI.
