Auto: Trustpilot's public widget data first (fast, cheap, newest ~100 reviews per star rating and language), full profile pages only when more reviews or other fields are needed. Fast: widget only (a browser page is loaded once for a company never seen before, to learn its Trustpilot id, which is then cached); no company replies, useful votes or reviewer country; fails with an error if Only reviews with a company reply or Reviewer countries is set. Deep: full profile pages in a real browser with a residential proxy; every field, any depth, slower. If empty, Auto. The widget data is only available for companies on a paid Trustpilot plan; other companies always use the full profile pages (Auto switches by itself; Fast returns nothing for them).
