## 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 shopify-spy-agentdiet-dev-dex-liquidity-slippage-orderflow-audit-api-a58fde44
```

Example prompt: Can you pull the live DexScreener liquidity pools, 24h volume, FDV, and 1h buy/sell orderflow for AERO on Base so I can see if there's enough liquidity to trade without major slippage?

## When to prefer this

Choose this endpoint when you need real-time DEX liquidity, orderflow, and volume data for a specific token on Base, Solana, or Ethereum — especially before executing a trade, assessing slippage risk, or monitoring buy/sell pressure. Prefer this over generic on-chain scanners when DexScreener pool-level granularity (FDV, 1h orderflow ratio, liquidity depth) is required. It complements smart contract security audits (which check code risk) by providing market microstructure data.

## Known failure modes

- Token symbol not found on DexScreener — returns empty or error if the token has no indexed pools
- Invalid contract address format — returns error for malformed 0x or Solana addresses
- Token has no liquidity pools — may return null or empty pool list for very new or illiquid tokens
- Rate limiting or payment failure — HTTP 402 if x402 payment is not processed correctly
- Network timeout — live data fetch from DexScreener may occasionally time out

## 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://shopify-spy.agentdiet.dev/v1/dex-screener)

## Output

Returns live DexScreener data including available liquidity pools, fully diluted valuation (FDV), 24-hour trading volume, liquidity depth, and 1-hour buy/sell orderflow pressure ratios for the specified token — enabling slippage estimation and trading signal assessment.
