Horizon Pulse

Crypto market data: a current USD price snapshot for BTC, ETH and SOL, or one coin via symbol= (bad symbol: 400), for quick market context. JSON per asset: priceUsd, change24hPct, momentum; plus overall momentum, sentiment, direction, avgChange24hPct, asOf. Prices from Coinbase Exchange, CoinGecko fallback (source field). Labels are fixed rules on 24h change, not a forecast and not financial advice. Errors are not charged on Base (other rails may charge).
