What it does
Online discourse sample, NOT a poll. Use to see how public Hacker News and Bluesky posts split on a question. GET with required q; optional sides (2-4, default yes,no), window (1-30d). Returns JSON: per-side share with 95% interval and n, counts per source, links only (no text or usernames; Bluesky links include the account's public ID, DID), caveats. Refuses elections, health and a named person's conduct. Under 30 decided posts, refusals and errors: not charged.
