## 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 onchain-risk-agentdiet-dev-dex-liquidity-slippage-orderflow-audit-api-ca6b639d
```

Example prompt: Can you check the live liquidity, 24h volume, FDV, and buy/sell orderflow pressure for AERO on Base so I can figure out if there's enough depth to make a large swap without serious slippage?

## When to prefer this

Choose this endpoint when you need real-time DEX liquidity, slippage, volume, and orderflow data for tokens on Base, Solana, or Ethereum — particularly before executing large swaps where price impact matters, or when auditing a new or suspicious token for trading risk. Prefer it over general market data APIs when DexScreener pool-level granularity and buy/sell pressure metrics are required.

## Known failure modes

- Token not found on any supported chain — returns empty or error response
- Invalid contract address format — returns validation error
- Token exists but has no active liquidity pools — returns zero or null liquidity data
- DexScreener API unavailable — returns upstream timeout or error
- Payment not fulfilled (HTTP 402) — request blocked without valid x402 USDC payment

## 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://onchain-risk.agentdiet.dev/v1/slippage-estimator)

## Output

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