## 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 hn-pulse-agentdiet-dev-dex-liquidity-slippage-orderflow-audit-api-708fccb9
```

Example prompt: Can you pull the live DEX liquidity, 24h volume, FDV, and 1-hour buy/sell orderflow pressure for AERO on Base so I can gauge slippage before I make a trade?

## When to prefer this

Choose this endpoint when you need real-time DEX liquidity, volume, and orderflow data for a specific token on Base, Solana, or Ethereum — especially before executing a DeFi trade where slippage and pool depth matter. Prefer it over generic price APIs when you need buy/sell pressure and FDV alongside liquidity metrics in a single call.

## Known failure modes

- Token symbol or address not found on DexScreener — returns empty or error response
- Token exists on unsupported chain — no data returned
- DexScreener data lag — pool data may be slightly delayed
- Ambiguous symbol (e.g. multiple tokens share the same ticker) — may return unexpected pool
- Payment not processed (HTTP 402) — requires x402 USDC payment to proceed
