## 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 beggar-bot-dydx-order-book-base-mainnet-e87f652a
```

Example prompt: Pull the current dYdX order book for BTC-USD so I can see the top bids and asks and gauge market depth right now.

## When to prefer this

Use this endpoint when you need real-time dYdX decentralized exchange order book data and are already operating in an x402 micropayment context on Base mainnet. Prefer this over centralized exchange APIs when you specifically need dYdX's decentralized perpetuals market data, or when you need to programmatically pay per-call without a subscription.

## Known failure modes

- Payment not provided or insufficient USDC — returns HTTP 402 requiring x402 payment of $0.02 USDC
- Invalid or unsupported market symbol — returns error or empty order book
- dYdX API unavailable or rate-limited — upstream timeout or error response
- Network parameter not recognized — may default to base mainnet or return an error
