## 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-candlestick-pattern-detection-api-c8ec1068
```

Example prompt: What candlestick patterns are currently showing up on the ETH 4h chart? I want to know if there are any bullish formations right now.

## When to prefer this

Use this endpoint when you need real-time candlestick pattern detection for crypto or stock tickers, especially when you want structured bullish/bearish pattern signals (e.g. engulfing, hammer) at specific intervals. Prefer this over generic charting APIs when you need OwlChart's proprietary pattern recognition paired with their TBO breakout signal methodology.

## Known failure modes

- Invalid or unsupported symbol returns an error or empty pattern list
- Unsupported interval value (outside 15m, 1h, 4h, 1d) may return an error
- No patterns detected returns an empty latest array
- Payment failure (insufficient USDC balance for x402 protocol) blocks the request
- Rate limiting if called too frequently without proper payment headers

## How this service works

Live crypto and stock market console: OwlView charts, TBO breakout signals, order books from 34 exchanges, ETF flows, funding, liquidations and Fed odds.

## Output

A JSON object containing the symbol, interval, and a 'latest' array of detected candlestick patterns, each with a 'pattern' name (e.g. 'Bullish engulfing') and 'side' field indicating bullish or bearish direction.
