Using Clay for LinkedIn Scraping: Does It Use Clay Credits?

Hi. I'm thinking of using Clay. I have my own spreadsheets I can upload with Name, Title, Email, Company, and in many cases LinkedIn URL. I need to have Clay scrape LinkedIn, confirm the Company, how long they've been there, and make a determination if they are in Private Practice, or work for a large company, and perhaps how long they've been at that company. Does a workflow like that use Clay Credits if I use my own API keys.
