[superhero general] Hey can I be a superhero for a living? Like can I get a sponsor that pays me for using my powers to fight crime?

Hey I’m 19 and I’m a metahuman with super powers. My power is to create ice that freezes things then explode after 10 seconds. I have the dream of being a hero but I don’t want to get a regular job. So is it possible for me to get payed for being a hero? Is it possible to be sponsored as a hero by companies so I can make a profit? Will I have to give up my secret identity? I just want to be able to afford food, a house, and having my costume fixed up when it gets torn up so I can focus on being a hero.

Depends on the universe               
Some of them are under the table government employees (MCU gives this implication)                  
Some can't receive sponsorship because signing contracts would open them up to litigation               
Some depend on private wealth or private benefactors               
Some work regular jobs                
                     
As far getting paid to be a hero... that's doesn't sound very heroic.  It sounds a lot more like setting yourself up to be an unknowing bad guy.  Endorsements are a nice idea but the money trail would ruin your anonymity and you would likely fight off law suits for the rest of your life.
