## 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-crypto-heatmap-price-magnet-levels-4c63fe64
```

Example prompt: Pull up the OwlChart heatmap for BTC and tell me where the nearest price magnets are above and below current price, and whether the market is being pulled up or down.

## When to prefer this

Use this endpoint when you need real-time liquidity cluster (price magnet) data for a specific cryptocurrency — particularly the concentration of large limit orders above and below current price and the net directional pull signal. Prefer this over generic order book APIs when you want pre-processed magnet-level analysis rather than raw order book depth.

## Known failure modes

- Invalid or unsupported coin ticker returns an error
- Missing required 'coin' query parameter causes a 400-level error
- Endpoint may return stale data if the upstream exchange feed is delayed
- Rate limiting or payment failure if x402 payment is not properly attached

## 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

Returns a JSON object containing: the coin ticker, a directional pull signal ('up' or 'down'), the current price in USD, a list of magnet levels above the current price (each with USD liquidity size and price), and a list of magnet levels below the current price (each with USD liquidity size and price).
