## 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 owlchart-candles-live-ohlc-price-data-80d7c9f4
```

Example prompt: Pull the latest 1-hour OHLC candle for BTC from OwlChart so I can see the current high, low, last price, and percent change.

## When to prefer this

Choose this endpoint when you need live, real-time OHLC candlestick data for crypto or stocks, especially when you want multi-exchange coverage (34+ exchanges), support for perpetual futures, and flexible time intervals from 1-minute to monthly. Prefer it over generic price APIs when you need structured OHLC candles rather than just a spot price, or when you need coverage of exotic exchange-specific instruments.

## Known failure modes

- Unknown or unsupported ticker symbol returns an error or empty response
- Invalid interval value (not one of the supported enum values) causes a bad request error
- Rate limiting or payment failure returns HTTP 402
- Exchange data temporarily unavailable may return stale or null values
- Perpetual vs spot symbol confusion (e.g. BTC vs BTCUSDT perp) may return unexpected instrument
