## 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 coingecko-ohlc-candlestick-data-03040df3 -d '<json body>'
```

Example prompt: Can you get me the OHLC candlestick data for Bitcoin (coin ID: bitcoin) vs USD for the last 30 days so I can see its price action?

## When to prefer this

Use this endpoint when you need structured OHLC candlestick price history for a specific cryptocurrency for technical analysis, charting, or trading signal generation. Prefer this over simple price lookups when you need open/high/low/close granularity rather than just current or average price.

## Known failure modes

- Invalid coin ID returns an error or empty response
- Unsupported days value (not in 1,7,14,30,90,180,365) may return an error
- Unsupported vs_currency value returns an error
- Network or upstream CoinGecko API unavailability causes failure
- Payment failure if x402 micropayment is not properly handled
