Get Onchain Health Score

GET/v1/cryptodata/on-chain/score

Composite 0-100 on-chain health score with per-component breakdown. Synthesizes Hash Ribbon, MVRV, stablecoin dry-powder, whale accumulation, exchange flow direction, and miner net flow into a single directional read. Sentiment bands: - **bullish** (≥70): broad on-chain confluence of accumulation signals - **leaning_bullish** (55-69): tilted positive but mixed - **neutral** (45-54) - **leaning_bearish** (30-44) - **bearish** (<30): broad distribution + miner stress + flow into CEXs Kept separate from `/market-health` for v1. Components with no data yet are EXCLUDED and the remaining weights renormalised, so a partially-warm deploy reports the confluence it can actually see instead of being diluted toward a confident-looking 50. When no component has data, `sentiment` is `unknown`. `whale_accumulation` is currently always unavailable (whale tracking is disabled, see `/on-chain/whales`): it reports `reason: "no_data"`, its `score` of 50 is a placeholder and it carries weight 0, so it does not move the composite. `exchange_flow` scores the USDT/USDC/DAI 24h net only; before 2026-10-08 it also summed other tokens in their native units, so its `reason` magnitudes from then are not dollars.
