What is OP_SCAN_API_KEY in .env.example

[Abhinav Prakash]

Hi,
Can anyone help me with what is "OP_SCAN_API_KEY" that has been used in .env.example?
How to get this API Key and what purpose does it serve here?

Hey there! This env variable is used to verify contracts on optimistic etherscan. You can get an API key here.
