## 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 chainray-online-a56a6e96
```

Example prompt: What's the liquidity depth for the WETH/USDC pair on Base — I want to know how deep the market is before placing a large trade.

## When to prefer this

Use this endpoint when you need on-chain liquidity depth for a specific token pair before executing a swap or assessing price impact. Prefer over generic market data APIs when you need granular DeFi liquidity metrics on EVM chains like Base.

## Known failure modes

- Token pair not found or unsupported — returns 404 or empty result
- Unsupported chain specified — returns error indicating invalid chain
- Missing required tokenA or tokenB query parameters — returns 400 bad request
- Low or zero liquidity for the pair — returns empty depth data
- Network or upstream data provider unavailable — returns 503
