## 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 crypto-price-history-ohlc-54f29989 -d '<json body>'

Example prompt: Can you pull the last 48 hourly OHLC candles for ETH so I can see how the price has been moving?

## When to prefer this

Choose this endpoint when you need structured historical candlestick (OHLC) price data for a specific cryptocurrency at a defined time interval. It is ideal for charting, backtesting trading strategies, or analyzing price momentum. Prefer it over spot-price endpoints when you need time-series granularity rather than a single current price.

## Known failure modes

- Unknown coin symbol returns an error or empty result
- Limit exceeding 500 is rejected
- Invalid interval value outside the allowed enum is rejected
- Network timeout for large candle requests
- Missing required coin parameter causes a validation error

## How this service works

Crypto price history as OHLC candles from on-chain perp DEXs: open/high/low/close, base volume and trade count per interval (1m, 5m, 15m, 1h, 4h, 1d) for a coin (BTC, ETH, SOL, and more). Returns up to 500 candles, oldest first. Data source: Hyperliquid (dYdX fallback).

## Output

Returns a series of OHLC candlestick records for the requested cryptocurrency, each containing open, high, low, and close prices along with a timestamp, ordered from oldest to most recent, up to the requested limit of candles.
