## 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 defi-yield-agentdiet-dev-dex-liquidity-slippage-orderflow-audit-api-cbf438f9
```

Example prompt: What's the current liquidity, FDV, 24h volume, and buy/sell orderflow pressure for AERO on Base? I want to know if there's enough depth to trade without major slippage.

## When to prefer this

Choose this endpoint when you need real-time DEX liquidity depth, slippage estimates, and orderflow pressure for a specific token before executing or recommending a trade. It is best suited for DeFi agents that need to assess whether a token has sufficient on-chain liquidity to trade without excessive price impact, or to monitor short-term buy/sell momentum on Base, Solana, or Ethereum.

## Known failure modes

- Unknown or unlisted token symbol returns empty or error response
- Token contract address on unsupported chain returns no pool data
- DexScreener API unavailability causes upstream timeout
- Invalid contract address format causes parameter validation failure
- Low-liquidity tokens may return sparse or incomplete pool data
