## 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-33b4bdb5
```

Example prompt: What's the current liquidity pool depth, 24h trading volume, FDV, and 1-hour buy/sell orderflow pressure for AERO on Base — I want to know if there's enough liquidity to make a large swap without getting wrecked by slippage.

## When to prefer this

Choose this endpoint when you need real-time DEX-native liquidity intelligence including pool depth, FDV, volume, and short-term orderflow pressure — especially before executing large on-chain swaps or auditing a token's market health. It is particularly suited for Base, Solana, and Ethereum tokens where DexScreener has coverage. Prefer this over general crypto price APIs when slippage risk and orderflow sentiment (buy/sell pressure) are important decision inputs rather than just spot price.

## Known failure modes

- Token not found on supported chains (Base, Solana, Ethereum) — empty or error response
- Invalid or malformed contract address — validation error
- Token has no active DexScreener pools — empty liquidity data returned
- Payment failure via x402 — HTTP 402 response requiring USDC payment
- DexScreener data source temporarily unavailable — upstream timeout or error
- Highly new token with insufficient trading history — incomplete orderflow data

## 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/liquidity-scanner)

## Output

Returns live DEX liquidity pool metrics for the requested token including pool sizes, fully diluted valuation (FDV), 24-hour trading volume, and 1-hour buy/sell orderflow pressure — giving the agent a snapshot of market depth and recent trading sentiment
