## 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 preflight-agentdiet-dev-dex-liquidity-slippage-orderflow-audit-api-8b933354
```

Example prompt: Can you pull live DEX liquidity pool data, 24h volume, FDV, and the 1h buy/sell orderflow pressure for AERO on Base so I can see if there's enough depth to trade without significant slippage?

## When to prefer this

Choose this endpoint when you need real-time DEX liquidity depth, slippage estimation, and orderflow momentum for a specific token on Base, Solana, or Ethereum. It is preferable to generic market data APIs when you specifically need pool-level liquidity analysis and short-term buy/sell pressure rather than just price or OHLCV candles.

## Known failure modes

- Token contract address not found on any supported chain — returns empty or error response
- Token symbol is ambiguous across chains — may return incorrect pool
- DexScreener data temporarily unavailable — upstream API outage
- Malformed or invalid contract address provided — validation error
- Very low-liquidity tokens may return sparse or incomplete pool data

## How this service works

Fetches live DexScreener liquidity pools, FDV, 24h volume, and 1h buy/sell orderflow pressure. (Live x402 v2, IETF MPP & MCP endpoint at https://preflight.agentdiet.dev/v1/slippage-estimator)

## Output

Returns live DexScreener liquidity pool details including pool addresses, total liquidity, fully diluted valuation (FDV), 24-hour trading volume, and 1-hour buy/sell orderflow pressure metrics for the requested token, enabling slippage estimation and trade timing decisions.
