## 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 basebuilder-defi-dex-pool-liquidity-54fd039e -d '<json body>'
```

Example prompt: Can you pull up the liquidity data for the USDC/ETH pool on Base — I want to know the total reserves and TVL for that trading pair on the DEX.

## When to prefer this

Use this endpoint when you need on-chain liquidity data for a specific DEX pool on the Base blockchain, especially for DeFi analytics, arbitrage research, or assessing slippage risk for a trade. Prefer this over generic blockchain explorers when structured pool-level liquidity metrics are needed programmatically.

## Known failure modes

- Invalid pool address returns 400 or empty result
- Pool not found on the specified DEX returns null or error
- Unsupported DEX identifier causes 422 error
- Network issues with Base RPC cause timeout or 503
- Rate limiting or payment failure causes 402 response
