Online Hackathon prize money taxation and exceptions

I’ve participated in one of the Hackathon competition on DevPost and won the prize amount of $3000 USD.

However, the claiming section asked me to fill-up the W-8BEN tax form as I’m not a US resident. The form has a field for income type, but not sure about few things.

1. What should need to be filled in income type?

2. It is not a lucky draw or kind of gambling though, will I have to pay tax to the US government?

3. Is there any chance to claim 0% taxes from the US government? or another exception?

4. What will be the final amount I will receive on-hand?

Other note:
I individually won the award, there is no other team member to share this amount with.
