## 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 blockrun-ai-d606acf7
```

Example prompt: Can you pull the liquidation chart data for BTCUSDT so I can see how liquidations have trended over time?

## When to prefer this

Use this endpoint when you need time-series liquidation chart data for a specific crypto trading pair (e.g. BTCUSDT). Prefer this over OHLCV endpoints when the user specifically wants to analyze forced liquidations rather than price/volume data. Choose this when monitoring leveraged market stress or liquidation cascades.

## Known failure modes

- Missing required 'symbol' query parameter returns an error
- Invalid or unsupported trading symbol returns empty or error response
- Rate limiting or insufficient payment (x402) results in 402 Payment Required
- Network timeout for large datasets
- Symbol not supported on the underlying data source

## How this service works

Pay for the outcome. One endpoint for every model, tool and data source an agent needs — each call priced before it runs, at the best value per dollar. 103 models and 100 data and tool APIs.

## Output

A time-series dataset (likely truncated at ~47KB raw) containing liquidation amounts over time for the requested trading symbol, suitable for charting or analysis of forced position closures in the crypto derivatives market.
