Horizon Pulse
GET https://horizonpulse.dev/api/signals
Crypto technical analysis. Use when you need indicators for BTC, ETH and SOL rather than just prices. Call GET with no parameters. Returns JSON per asset: rsi14, macd {macd, signal, histogram} (null when there are too few candles), bollinger {upper, middle, lower, period}, lastClose and OKX perpetual funding {fundingRate, fundingTime}. Computed from CoinGecko OHLC closes (Coinbase candles fallback); methodology included. Descriptive only, not advice. Errors are not charged.
How to buy
This endpoint takes pay-per-call payments over x402. Call it once without paying to see its live price; any x402 client then pays and retries automatically.
