## 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-5653a4e6
```

Example prompt: Can you pull the live liquidity pool data, FDV, 24h volume, and 1-hour buy/sell orderflow pressure for AERO on Base — I want to know if there's enough depth to trade without getting wrecked by slippage.

## When to prefer this

Choose this endpoint when you need real-time DEX liquidity depth, orderflow pressure, and volume metrics for tokens on Base, Solana, or Ethereum — especially before executing swaps where slippage is a concern, or when building DeFi trading signals. Prefer this over general token price APIs when the 1-hour buy/sell orderflow split and pool-level liquidity depth are specifically needed for trading decisions or risk assessment.

## Known failure modes

- Token symbol or address not found on supported chains — returns empty or error response
- Token exists but has no active DEX liquidity pools — returns zero or null pool data
- Rate limiting or payment failure (HTTP 402) if x402 payment is not properly attached
- DexScreener API upstream delay or outage causing stale or missing data
- Ambiguous token symbol matching multiple tokens — may return incorrect pool

## 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/raydium-liquidity)

## Output

Returns live DEX liquidity pool data including pool addresses, liquidity depth, fully diluted valuation (FDV), 24-hour trading volume, and 1-hour buy versus sell orderflow pressure — giving agents a real-time snapshot of market microstructure for the queried token.
