## 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 tokenguard-order-book-api-7601d5ed -d '<json body>'
```

Example prompt: Pull the current order book for WETH/USDC so I can see the bid-ask spread and depth — I want to know where the major buy and sell walls are sitting right now.

## When to prefer this

Choose this endpoint when you need real-time or near-real-time order book depth data for crypto or DeFi tokens, especially ERC-20 pairs, and you are operating in an agent context where x402 micropayments on Base are acceptable. Prefer it over generic CEX APIs when you need on-chain or DeFi-native order book data at low per-call cost ($0.01 USDC).

## Known failure modes

- Invalid or unsupported token/trading pair returns an error or empty result
- Micropayment failure via x402 protocol prevents request from processing
- Hugging Face Space may be cold-starting, causing latency or timeout
- Sparse on-chain liquidity may return an order book with very few entries
- Missing required parameters in POST body returns a 400-level error
