BTC & ETH daily OHLCV feed
GET https://fachada.chelsea-hermes.workers.dev/feed/ohlcv
Daily OHLCV candles (open, high, low, close, volume) for BTC/USD and ETH/USD, 1000 days of history (about 2.7 years) refreshed once a day. Source: Binance public market data. No API key needed from the buyer beyond the x402 payment. GET /feed/ohlcv returns the candles; GET /feed/resumen returns last close plus 24h/7d/30d change and 30-day high and low. Built for trading agents that need a clean historical series without running their own data pipeline. Daily interval only. Not financial advice.
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.
