## 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 agentdatum-crypto-order-book-depth-9488b383
```

Example prompt: Pull up the live order book depth for BTCUSDT — show me the buy and sell walls aggregated across Binance, OKX, and Coinbase, top 20 levels.

## When to prefer this

Choose this endpoint when you need real-time, multi-exchange order book depth rather than just a single spot price. It is ideal for pre-trade analysis, detecting large buy/sell walls, assessing market liquidity, or monitoring microstructure across Binance, OKX, and Coinbase simultaneously — rather than querying each exchange individually.

## Known failure modes

- Missing or invalid 'symbol' parameter returns a validation error
- Unsupported trading pair symbols may return empty or error responses
- Rate limiting or downstream exchange API outages may cause partial or failed data
- Network timeouts during high market volatility periods
