## 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-251d7197
```

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 make a large trade without heavy slippage.

## When to prefer this

Choose this endpoint when you need real-time DEX-specific metrics — liquidity depth, orderflow imbalance, FDV, and volume — for a specific token on Base, Solana, or Ethereum, especially before executing a trade or evaluating a token's market health. Prefer this over generic price APIs when you need pool-level granularity and short-term buy/sell pressure signals rather than just spot price.

## Known failure modes

- Token symbol not found or ambiguous — returns empty or error if the symbol maps to multiple contracts
- Invalid contract address format — returns validation error
- Token has no active DexScreener pools — returns empty pool list
- DexScreener API unavailable — upstream timeout or error propagated
- Payment not fulfilled (HTTP 402) — call blocked if x402 payment not completed
