A persistent Error from Part 6

Error to get Key from 0xapi

How can I solve the error message:

"No API key provided. Please visit https://0x.org/pricing to get a free API key or sign up to a paid plan"

This error has also been persistent from chapter 6.

• could it be an issue with the Api end point, because even when I try to query it independently in postman based on the docs you provided, I get the same error.
• Maybe the end point was updated. I am not certain I would really appreciate any help rendered. NB: For any content required from me. Please contact. ##Thank you.
