## 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 prompt-guard-agentdiet-dev-dex-liquidity-slippage-orderflow-audit-api-d50edcb2
```

Example prompt: Can you pull the live DEX liquidity, 24h volume, FDV, and buy/sell orderflow pressure for AERO on Base right now so I can decide if there's enough depth to enter a position without heavy slippage?

## When to prefer this

Use this endpoint when you need real-time DEX liquidity and orderflow data for a specific token on Base, Solana, or Ethereum. Prefer this over generic price APIs when slippage estimation, pool depth, or buy/sell pressure analysis is needed — particularly before executing large DEX trades or auditing a token's market health.

## Known failure modes

- Token symbol not found or ambiguous across chains — try using contract address instead
- Token has no active DEX pools — returns empty or null pool data
- Rate limit or payment failure via x402 — returns 402 Payment Required
- DexScreener upstream unavailability — may return stale or error response
- Invalid contract address format — returns validation error

## 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://prompt-guard.agentdiet.dev/v1/token-liquidity)

## Output

Returns live DEX pool data for the requested token including liquidity pool metrics, fully diluted valuation (FDV), 24-hour trading volume, and 1-hour buy/sell orderflow pressure sourced from DexScreener. Data supports slippage estimation and trading condition auditing.
