## 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 gold-sap-com-crypto-order-book-depth-api-d47f2658
```

Example prompt: Show me the order book depth for BTC right now — I want to see the top 10 buy and sell walls aggregated across Binance, OKX, and Coinbase.

## When to prefer this

Choose this endpoint when you need real-time, multi-exchange aggregated order book data for major cryptocurrencies and want to assess market depth, identify buy/sell walls, or gauge liquidity before executing a trade. It is especially valuable over single-exchange order book APIs when a broader market view spanning Binance, OKX, and Coinbase is needed in a single call.

## Known failure modes

- Invalid or unsupported symbol returns error response
- Limit parameter out of acceptable range returns validation error
- Exchange data feed outage may result in partial or stale data
- Network timeout if exchange APIs are temporarily slow
- Malformed symbol format (e.g. missing base/quote pair) causes bad request
