Returns a stored prefill result by the prefillId its lookup returned, with the kind of lookup that produced it (lookupType). A null profile means that lookup found no match. Reading a stored result is not billed and never contacts the provider. Where the lookup found an EIN, the returned tin object (tinType, tin, lastFour) is for checking the one the applicant types; it never replaces it, and entity create still requires the full typed EIN. Results are unverified commercial data (dataClassification unverified_commercial_data) for filling onboarding forms. They never verify a business, change CIP, or feed KYB decisioning.
