## 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 coin-railz-dex-liquidity-pool-monitor-01264e6c -d '<json body>'
```

Example prompt: Can you pull the current DEX liquidity pool data for the WETH token at contract address 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2 on Ethereum — I need to see total liquidity in USD and which pools it's in?

## When to prefer this

Use this endpoint when you need real-time, cross-DEX liquidity aggregation for a specific token on a given blockchain — particularly useful before executing a large trade to assess slippage risk, when evaluating a new DeFi token's tradability, or when monitoring liquidity health over time. Prefer this over CEX order book tools when the focus is on on-chain decentralized liquidity.

## Known failure modes

- Invalid or non-existent token contract address returns empty pools array
- Unsupported chain name returns an error or no results
- Token with no DEX liquidity returns zero totalLiquidity
- Network congestion may delay real-time data freshness
- Malformed tokenAddress (not a valid contract format) causes validation error

## How this service works

Real-time DEX liquidity pool monitoring across multiple exchanges

## Output

Returns an array of liquidity pool objects across multiple DEXes for the specified token, plus a totalLiquidity field representing the aggregate USD value of all liquidity found for that token on the given chain
