## 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-cd9be514
```

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

## When to prefer this

Choose this endpoint when you need real-time DEX market intelligence — specifically liquidity depth, FDV, volume, and short-term orderflow pressure — for tokens on Base, Ethereum, or Solana. Prefer it over general price APIs when slippage estimation or buy/sell momentum analysis is required before executing a trade or assessing token health.

## Known failure modes

- Token not found on supported chains — returns empty or null pool data
- Invalid contract address format — may return error or no results
- Token exists on unsupported chain — data unavailable
- DexScreener upstream outage — stale or missing data returned
- Payment failure (HTTP 402) if x402 micropayment not completed
