Composite cotton view: futures + CFTC COT positioning + trend.

Composed DAO governance translator. Takes a Snapshot or Tally proposal URL, fetches structured data + summary via /api/governance/summarize, then produces a 2-3 sentence plain-language translation + domain band (economic_param / treasury / code_upgrade / governance_meta / social_signal). 1-year cache — proposals are immutable.

ADX-based chop-vs-trend detector for an asset/timeframe: is price trending or stuck in a range? Returns a boolean + chop score. Use to avoid trend strategies in chop (and range strategies in trends).

Fiat FX rates + amount conversion over free public APIs (Frankfurter/ECB primary, open.er-api fallback, 160+ currencies). Fiat-to-fiat, distinct from crypto /price.

BTC and ETH market-cap dominance (% of total crypto market cap), plus total market cap and active-coin count, refreshed every ~5 min. Use to gauge whether capital sits in majors vs alts. For the alt-rotation read specifically, use /alt-season.

BTC or LTC halving countdown: blocks remaining and the estimated date of the next halving. Use for cycle-timing narratives and supply-shock context. Estimate (block-time based), not an exact timestamp.

Composite cashew view: farmgate + wholesale + trend.

Current BTC market regime — BULLISH / BEARISH / NEUTRAL — derived from price vs its 20-period EMA on the 12h candle, with the EMA value and slope. The top-level risk filter: trade-with-trend context before any entry. BTC-based; pair with per-asset tools for alts.

Aggregated market sentiment label (strong_bearish → strong_bullish) with a normalized score, computed from LLM-scored news over the window. One-number mood read for an agent that just needs the verdict, not the individual articles.

Recent crypto news headlines each scored 1-10 for trading impact by an LLM (qwen3:8b), with a bullish/bearish/neutral tag. Filter by category, minimum score and lookback hours. Use to surface market-moving stories; for the aggregate read use /sentiment/summary.

Pearson correlation of a coin's returns vs BTC (-1 to +1) over the period. Use to judge diversification and whether an alt is moving independently or just tracking BTC. A correlation coefficient, not a beta or causation claim.

Bollinger-Band squeeze detector: is volatility compressing toward a likely expansion? Returns extreme/strong/moderate/none plus bandwidth. Use to anticipate breakouts before they fire. Detects the setup, not the direction.

Realized volatility for an asset: daily and annualized %, plus a low/normal/high/extreme bucket and the 24h high/low/range. Use to size positions and set expectations. Backward-looking (realized), not implied/option vol.

Alt-season detector: what % of the top-10 alts have outperformed BTC over the lookback window, with a 0-100 index and a boolean verdict. Use to time BTC↔alt rotation. Complements /dominance (capital location) with relative-performance signal.

Relative strength of a coin vs BTC over a period, returned as a category (very_strong → very_weak) plus a numeric score. Use to rank a coin's momentum against the benchmark before entering. A strength read, not a price target.

Top and bottom momentum coins ranked by return over the chosen period — a leaderboard of what's running and what's bleeding. Use to surface rotation candidates. Returns ranked movers, not full fundamentals.
