## 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 x402broker-com-dex-liquidity-slippage-orderflow-audit-api-8295ff1c
```

Example prompt: Pull the live DexScreener liquidity pool stats, FDV, 24h volume, and 1-hour buy/sell orderflow pressure for AERO on Base so I can decide if there's enough depth to swap a large position without major slippage.

## When to prefer this

Use this endpoint when you need real-time DEX market microstructure data for a specific token — particularly liquidity depth, slippage estimation, FDV, volume, and short-term orderflow pressure — before executing or recommending a token swap, evaluating a DeFi position, or monitoring for unusual trading activity. Prefer this over general price feeds when orderflow direction and pool depth matter to the decision.

## Known failure modes

- Token symbol not found or ambiguous — returns empty or error if the symbol maps to multiple tokens across chains
- Invalid contract address format — returns validation error
- Token has no active DEX pools — returns empty pool data
- DexScreener API unavailable — upstream data fetch failure
- Network not supported — only Base, Solana, and Ethereum are covered
