## 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-0c23b053
```

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 make a large trade without serious slippage?

## When to prefer this

Choose this endpoint when you need real-time DEX market intelligence — specifically liquidity depth, slippage estimation, or buy/sell pressure — for tokens on Base, Solana, or Ethereum. It is ideal for pre-trade due diligence, on-chain risk audits, or detecting orderflow imbalances. Prefer it over generic price APIs when you need pool-level liquidity data and 1-hour orderflow direction, not just a spot price.

## Known failure modes

- Unknown or unlisted token symbol/address returns empty or error response
- Token not present on Base/Solana/Ethereum may return no pools
- Stale or low-liquidity tokens may return zero volume data
- Invalid contract address format causes a validation error
- DexScreener upstream unavailability may result in timeout or degraded response
- Payment failure (x402) blocks the request if USDC balance is insufficient

## 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/dex)

## Output

Returns live DEX data for the requested token including liquidity pool details, fully diluted valuation (FDV), 24-hour trading volume, and 1-hour buy/sell orderflow pressure metrics sourced from DexScreener, enabling assessment of market depth and trading dynamics.
