Is the question "did you request for the bill" correct? [closed]

Really confused here and can't find anything online. I think the correct usage will be "did you request the bill", but not sure if "did you request for the bill" is correct too?

The word request can be either a noun or a verb. The verb to request is transitive and so has a direct object. So you say:

I am going to my boss to request compassionate leave

Alternatively you can use the noun and say

I am going to put in a request for compassionate leave.

Where there might be a confusion is that of you replace the word request with the word ask, then you do have to use the preposition for and say:

I am going to my boss to ask for compassionate leave.

It is true that even the word ask can sometimes (in a strictly limited and idiomatic context) be use as a noun.

You want me to look after your pet python for the entire month you are on holiday? That's a huge ask.

But you would not talk about putting in an ask for compassionate leave to your boss. It would be correctly understood but mark you out not a fluent speaker of the language.
