Free, capped multi-topic preview of the person-grain direction: given up to 25 topic_ids, return a small sample (up to 25) of the top people (as HEMs), merged one row per person and annotated with which of the requested topics they matched, plus the total count of matching people. The merged (group_by=entity) shape is forced. Use it to show a teaser while configuring a source, then call the paid /api/v1/intent/people/multi to pull and pay for the full list.

Nothing is billed. It does not paginate (no cursor, no next_cursor) and never returns raw email; you always get the strongest-intent top of the merged list. Only floor filters are accepted; group_by, per_topic_limit, page_size, cursor, and resolve are not part of this request.
