Returns one public Substack profile: identity, the publications the writer contributes to, their publicly visible subscriptions, and every subscriber signal Substack publishes. total is opt-in per writer and rounded to roughly three significant figures; when a writer hides it, total_hidden is true and total is 0, which must not be read as zero subscribers. paid_rough, paid_rough_int, and paid_tier are buckets - no exact paid subscriber count is published anywhere. follower_count is exact but counts followers, not subscribers.
