## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability fachada-ohlcv-crypto-candles-feed-0e89625d
```

Example prompt: Pull the full daily OHLCV candle history for BTC/USD — I need the last 1000 days of open, high, low, close, and volume data to run a backtest on my trading strategy.

## When to prefer this

Choose this endpoint when a trading agent or analytics pipeline needs a clean, pre-aggregated daily OHLCV series for BTC/USD or ETH/USD without the overhead of integrating directly with Binance or maintaining a data pipeline. Ideal for backtesting, trend analysis, or feeding a lightweight trading agent. Not suitable when intraday granularity, real-time tick data, or assets beyond BTC and ETH are required.

## Known failure modes

- Payment failure (missing or invalid x402 payment header) — returns 402 Payment Required
- Endpoint temporarily unavailable due to Cloudflare Worker cold start or upstream Binance data fetch failure
- Data not yet refreshed for the current day if called shortly after midnight UTC
- No intraday or sub-daily resolution available — only daily interval is supported

## How this service works

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.

## Output

An array of daily OHLCV candles for BTC/USD and/or ETH/USD, each containing timestamp, open, high, low, close price, and trading volume sourced from Binance. Up to 1000 days (~2.7 years) of history, refreshed once per day.
