Dated strength history for one CoinBucha signal, newest first. Returns { as_of, signal_type, title, unit, count, points[], truncated, available_points, tier_window_points, freshness, why, disclaimer, cite }, where each point carries date, signal_strength (0-100) and direction (tailwind | headwind | neutral). Example: {"signal_type": "network_hashrate", "days": 30}. signal_type is one of sovereign_adoption, hiring_velocity, corporate_treasury, network_hashrate. Anonymous and free-tier callers receive the most recent points only and are told so by truncated and available_points; no figure is ever altered or interpolated to fit a window. A history question beyond that window is a bulk question: data_contract.bulk_url names the CSV of the signal's dated figures. Observational data; information, not financial advice. Every answer carries data_contract { source, as_of, status, corrections_url, license }. This server answers bounded questions, one question, one answer; for bulk, history, backfills and scheduled pulls use the CSVs and datapackage.json at https://coinbucha.com/data.
