Is Clay necessary for finding email and business mailing addresses compared to Claude with Google Sheets CLI?

Why use Clay if you can use Claude Cowork with Google Sheets through Google CLI, https://github.com/google-gemini/gemini-cli along with the Claude Chrome extension/WebFetch, to find and enrich the data? My use case: I have a person’s name & business name, and I just want their email and business' mailing address (Likely the LLC’s statutory agent mailing address from the secretary of state website) Given that, do I really need Clay? Help me see if I'm missing something here. Thank you in advance.
