crypto-sentiment-x402.onrender.com/history/:symbol

Historical crypto sentiment API: hourly news-sentiment readings for 24 coins, recorded live every UTC hour and never backfilled. Rows: observed_at, score (-1 to 1), sample size, Fear & Greed value and the top 3 headlines. Use when an agent needs past readings, e.g. to backtest or compare with price. Query start/end as ISO 8601: default last 7 days, max 30 per call. An unlogged coin, an invalid range, or a range with no readings or no headlines is refused and not charged. Coverage: /archive.
