Get News Pulse

GET/v1/cryptodata/news/pulse

Per-coin news feature series — `news_pressure` and signed `news_tilt`. The endpoint built for trading strategies: one row per Hyperliquid perp, cross-sectionally ranked, joinable straight onto price. - `news_pressure` (0..1) — recency-weighted sum of impact scores, saturating. - `news_tilt` (-1..+1) — impact-weighted direction. Negative is risk-off. - `event_count` / `top_impact` — how much of the pressure is one big story versus a steady drip. - `headlines` — raw coverage: how many stories in the current feed window name this coin at high confidence, whether or not any of them qualified as a catalyst. This is attention, not an event. The catalyst funnel discards ~95% of what it reads, so most coins sit at `news_pressure: 0` while `headlines` keeps counting; a coin high on headlines with no pressure is being talked about without anything happening. **Every active perp gets a row.** A coin with no news is `news_pressure: 0`, not a missing row — a cross-sectional ranking needs the zeros, and a silently absent symbol is indistinguishable from a pipeline failure. Rows are ranked by pressure first, then by `headlines`. Free tier gets the top 10 rows; Pro and above get the full universe.
