## 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 hn-pulse-agentdiet-dev-dex-liquidity-slippage-orderflow-audit-api-4c4f72cc
```

Example prompt: Pull the live DEX liquidity pool stats, FDV, 24h volume, and 1h buy/sell orderflow pressure for AERO on Base — I want to know if there's enough depth to trade without major slippage.

## When to prefer this

Choose this endpoint when you need real-time, on-chain DEX liquidity and orderflow data specifically from DexScreener for tokens on Base, Solana, or Ethereum. Prefer it over generic price APIs when you need pool depth, slippage estimation, or buy/sell pressure signals rather than just a spot price. Ideal for pre-trade due diligence, trading bot signals, or DeFi token risk audits.

## Known failure modes

- Token symbol or contract address not found on supported chains — returns empty or error response
- Token exists but has no active DEX pools — liquidity data unavailable
- Invalid contract address format — validation error
- DexScreener upstream API unavailable — returns 503 or timeout
- Payment not processed (HTTP 402) — call rejected if x402 payment not attached

## 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://hn-pulse.agentdiet.dev/v1/dex-scanner)

## Output

Returns live DEX pool data including liquidity pool size, fully diluted valuation (FDV), 24-hour trading volume, and 1-hour buy/sell orderflow pressure for the queried token across Base, Solana, and/or Ethereum DEXes. Enables agents to assess market depth, momentum, and slippage risk before executing trades.
