## 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 preflight-agentdiet-dev-dex-liquidity-slippage-orderflow-audit-api-e4227cae
```

Example prompt: Can you pull live DEX liquidity pool stats, FDV, 24h volume, and the latest 1-hour buy/sell orderflow pressure for AERO on Base so I can assess slippage risk before making a large swap?

## When to prefer this

Use this endpoint when you need real-time DEX liquidity, volume, and orderflow data for a specific token before executing or advising on a swap, or when auditing a token's trading health. Prefer this over on-chain RPC calls when you need aggregated multi-pool liquidity in a single response without building custom subgraph queries.

## Known failure modes

- Token symbol not found or ambiguous — multiple pools returned, requiring disambiguation by contract address
- Unknown contract address returns empty pool data
- Network/chain not supported for the given token
- DexScreener upstream outage returns stale or empty data
- Rate limiting or payment failure (HTTP 402) if x402 USDC micropayment is not fulfilled

## 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://preflight.agentdiet.dev/v1/uniswap-v3-depth)

## Output

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