crypto-sentiment-x402.onrender.com
Hourly crypto news-sentiment readings for a ticker (e.g. BTC, ETH), recorded live at the top of every UTC hour and never backfilled. Each row: observed_at, average_compound (-1 to 1), sample_size, Fear & Greed value, matcher and the top 3 headlines behind it (title, link). Query start/end as ISO 8601; default last 7 days, max 30 days per call. An unlogged symbol, an invalid range or a range with no readings is refused and not charged. See /archive for symbols and coverage.
