## 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 prompt-guard-agentdiet-dev-dex-liquidity-slippage-orderflow-audit-api-4ca53d82
```

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

## When to prefer this

Choose this endpoint when you need real-time DEX liquidity depth, orderflow pressure, and slippage estimates for tokens on Base, Solana, or Ethereum — especially before executing large on-chain trades or auditing a new token's market health. Prefer this over generic price APIs when orderflow imbalance and pool-level liquidity data are required.

## Known failure modes

- Unknown or unsupported token symbol returns empty or error response
- Contract address on unsupported chain returns no data
- Rate limiting or payment failure (HTTP 402) if USDC payment not provided
- DexScreener data unavailable or stale for illiquid tokens
- Malformed token address causes validation error

## How this service works

## Output

Returns live DexScreener data for the requested token including liquidity pool details, fully diluted valuation (FDV), 24-hour trading volume, and 1-hour buy/sell orderflow pressure metrics useful for slippage estimation and trade safety assessment.
