## 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-75edb16e
```

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

## When to prefer this

Choose this endpoint when you need real-time DEX market microstructure data — liquidity depth, FDV, volume, and buy/sell pressure — for a specific token on Base, Solana, or Ethereum. Prefer it over generic price APIs when slippage assessment, orderflow analysis, or liquidity auditing is the goal. It is especially useful when evaluating whether a token has sufficient market depth for a trade or when monitoring short-term momentum via 1h orderflow.

## Known failure modes

- Token not found on supported chains — returns empty or error if contract address is invalid or unlisted
- Network issues with DexScreener upstream — may return stale or partial data
- Unsupported chain — token may exist but not be indexed on Base/Solana/Ethereum
- Rate limiting or payment failure — HTTP 402 if payment is not properly attached
- Ambiguous symbol — a symbol like 'USDC' may match multiple contracts across chains

## 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/token-scanner)

## Output

Returns structured data from DexScreener including active liquidity pools, fully diluted valuation (FDV), 24-hour trading volume, and 1-hour buy/sell orderflow pressure metrics for the queried token on Base, Solana, or Ethereum.
