## 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 serp-extract-agentdiet-dev-dex-liquidity-slippage-orderflow-audit-api-17babe53
```

Example prompt: Pull the live DexScreener liquidity audit for AERO on Base — I want to see the pool depth, FDV, 24h volume, and whether buy or sell pressure is dominating over the last hour before I make a trade.

## When to prefer this

Choose this endpoint when you need real-time DEX liquidity and orderflow data sourced from DexScreener for tokens on Base, Solana, or Ethereum — especially before executing trades where slippage risk matters. Prefer this over general market data APIs when you specifically need pool-level liquidity depth, buy/sell pressure ratios, and FDV in a single call. It is particularly suited for on-chain DeFi trading agents, risk auditors, and portfolio managers evaluating token market health programmatically.

## Known failure modes

- Token symbol not found or ambiguous across chains — returns empty or mismatched pool data
- Invalid or unrecognized contract address — returns error or empty response
- Token exists but has no active DexScreener-indexed liquidity pools — empty pool array returned
- Payment not processed (HTTP 402) — request blocked due to missing or failed x402 USDC micropayment
- DexScreener upstream API unavailable — service timeout or 503 error
- Token on unsupported chain — only Base, Solana, and Ethereum are indicated as supported

## 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://serp-extract.agentdiet.dev/v1/dex-screener)

## Output

Returns structured DexScreener data including one or more liquidity pool records for the queried token, with fields covering FDV (fully diluted valuation), 24-hour trading volume, pool liquidity depth, and 1-hour buy/sell orderflow transaction counts and volumes, enabling slippage estimation and market sentiment assessment.
