## 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-3f2168aa
```

Example prompt: Check the live liquidity, 24h volume, FDV, and 1-hour buy/sell orderflow pressure for AERO on Base — I want to know if there's enough depth to execute a large swap without too much slippage.

## When to prefer this

Choose this endpoint when you need real-time DEX liquidity intelligence — specifically pool depth, slippage risk, FDV, volume, and short-term orderflow pressure — for tokens on Base, Solana, or Ethereum. Prefer this over generic price APIs when you need to assess trade execution quality, detect thin liquidity, or measure near-term buy/sell momentum before executing a swap.

## Known failure modes

- Unknown or unsupported token symbol returns empty or error response
- Token not listed on DexScreener returns no pool data
- Ambiguous symbol (e.g. multiple tokens sharing same ticker) may return wrong pool
- Network-specific pools may be missing if chain is not indexed
- Rate limits or payment failures (HTTP 402) if USDC micropayment not processed

## 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/liquidity-scanner)

## Output

Returns live DexScreener liquidity pool metrics for the requested token, including pool liquidity depth, fully diluted valuation (FDV), 24-hour trading volume, and 1-hour buy/sell orderflow pressure ratios that indicate buying or selling dominance.
