Crypto prices and ZEC ETF flows

Live USD prices for the top 100 cryptocurrencies by market cap: rank, name, symbol, price, 1h / 24h / 7d percent change, market cap and 24h volume. Data from CoinGecko, at most about 60 s old. Pass symbols (tickers like "btc", or CoinGecko ids / names like "ethereum") for specific coins, or omit them for the top N by market cap. Coins outside the top 100 are not available.

The current ZEC ETF flows indicator: a daily BUY / HOLD / SELL signal for Zcash built from creations and redemptions in US spot Zcash ETFs (Grayscale ZCSH), scored together with premium to NAV, derivatives leverage and funding, spot taker imbalance, open interest trend, shielded pool growth, volume share, SEC EDGAR filings and the price regime. Returns the signal, total score, each component's score and reason, the raw inputs, an LLM-written rationale (it may only downgrade the computed signal), the tracked funds and recent classified filings. Recomputed once a day after the US close; "stale" is true when the ETF data is more than two business days old. Informational only, not investment advice.
