## 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-4cc9a8fe
```

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

## When to prefer this

Use this endpoint when you need real-time DEX liquidity, orderflow, and market depth data for a specific token on Base, Solana, or Ethereum — especially for pre-trade slippage checks, on-chain market surveillance, or DeFi due diligence. It is backed by DexScreener live data and includes 1h buy/sell pressure not typically available through simple price APIs.

## Known failure modes

- Token symbol or contract address not found on DexScreener — returns empty or error response
- Token exists on unsupported chain — no data returned
- DexScreener data lag or outage — stale or missing metrics
- Malformed token input (invalid contract address format) — validation error
- Payment not fulfilled (HTTP 402) — request blocked until x402 micropayment is settled

## 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/pair-analytics)

## Output

Returns a JSON object containing live DEX liquidity pool details sourced from DexScreener, including fully diluted valuation (FDV), 24-hour trading volume, current liquidity depth, and 1-hour buy/sell orderflow pressure metrics for the requested token on Base, Solana, or Ethereum.
