## 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-566fcb0b
```

Example prompt: What's the current DEX liquidity, 24h volume, FDV, and buy/sell orderflow pressure for AERO on Base — I want to know if there's enough pool depth for a large trade without major slippage.

## When to prefer this

Use this endpoint when you need real-time DEX liquidity metrics, orderflow pressure, and pool depth for a token before executing a trade, assessing slippage risk, or monitoring market dynamics on Base, Ethereum, or Solana. Prefer this over generic price APIs when you specifically need pool-level liquidity data, buy/sell imbalance signals, or FDV alongside volume — not just spot price.

## Known failure modes

- Unknown or unlisted token symbol returns empty pool data or 404
- Contract address on unsupported chain returns no results
- Very new or low-liquidity tokens may have incomplete DexScreener data
- Invalid contract address format returns a validation error
- DexScreener API downtime causes upstream data unavailability
- Payment not completed (HTTP 402) blocks data retrieval

## 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-liquidity)

## Output

Returns structured data including active DEX liquidity pools (pool addresses, DEX name, token pair), fully diluted valuation (FDV), 24-hour trading volume, current liquidity depth, and 1-hour buy/sell orderflow pressure metrics sourced live from DexScreener.
