## 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-50ed5473
```

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

## When to prefer this

Use this endpoint when you need real-time DEX liquidity and orderflow data for on-chain tokens on Base, Solana, or Ethereum — especially before executing large trades where slippage is a concern, or when building trading bots that react to buy/sell pressure imbalances. Prefer this over general market data APIs when you specifically need pool-level liquidity depth, FDV, and short-term orderflow metrics sourced from DexScreener.

## Known failure modes

- Token symbol or contract address not found on DexScreener — returns empty or error response
- Token exists on an unsupported chain — data may be unavailable or incomplete
- DexScreener upstream API rate limit or downtime — may return 503 or timeout
- Ambiguous token symbol matching multiple tokens — may return incorrect pool data
- Very low-liquidity tokens may have sparse or missing orderflow data

## 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-liquidity-depth-oracle)

## Output

Returns live DexScreener data for the requested token including active liquidity pools, fully diluted valuation (FDV), 24-hour trading volume, and 1-hour buy/sell orderflow pressure metrics that can be used to assess market depth, slippage risk, and directional trading sentiment.
