## 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 x402-audit-agentdiet-dev-dex-liquidity-slippage-orderflow-audit-api-cc9bde13 -d '<json body>'
```

Example prompt: What's the current liquidity pool depth, FDV, 24h volume, and 1h buy/sell orderflow pressure for AERO on Base? I want to know if there's enough liquidity to do a large swap without too much slippage.

## When to prefer this

Choose this endpoint when you need real-time DEX liquidity and orderflow data for a specific token on Base, Solana, or Ethereum — especially when estimating trade slippage, auditing buy/sell pressure imbalances, or assessing pool depth before executing a large on-chain swap. It is purpose-built for DeFi trading intelligence and aggregates DexScreener pool data into a structured agent-ready response, making it preferable over raw DexScreener scraping or general-purpose blockchain APIs.

## Known failure modes

- Token symbol or contract address not found on supported chains — returns empty or error response
- Token exists but has no active liquidity pools on DexScreener — limited or null data returned
- Invalid contract address format — validation error
- DexScreener upstream API unavailable — service may return 5xx or timeout
- Payment not completed (x402) — request rejected before data is returned

## 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://x402-audit.agentdiet.dev/v1/slippage-estimator)

## Output

Returns live DEX pool data for the queried token including liquidity pool details, fully diluted valuation (FDV), 24-hour trading volume, and 1-hour buy/sell orderflow pressure metrics sourced from DexScreener, enabling slippage estimation and market microstructure analysis.
