    Returns the roles, places, industries and company sizes searched; the total
    count; five real example people (names blurred, companies unnamed) with a
    fit score; the buying signals Deberli tracks for that market; and a link
    that opens the full list in Deberli. Use it when the user asks who to sell
    to, how big their market is, or where to find customers or leads.
    Read-only. Takes 30-90 seconds.
