## 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-524a4b24
```

Example prompt: Can you pull the live DEX liquidity, FDV, 24h volume, and buy/sell orderflow pressure for AERO on Base right now so I can decide if it's safe to trade?

## When to prefer this

Choose this endpoint when you need real-time DEX liquidity, orderflow, and volume data for a specific token on Base, Solana, or Ethereum — particularly before executing a trade, assessing slippage risk, or monitoring market pressure. It is preferable over general crypto price APIs when you need pool-level depth and buy/sell flow data, not just price quotes.

## Known failure modes

- Token not found on any supported chain — returns empty or error if the symbol or contract address is unrecognized
- Invalid contract address format — malformed address strings will fail schema validation
- Token has no DEX pools — newly launched or illiquid tokens may return null liquidity data
- Rate limiting or payment failure — x402 micropayment not processed correctly results in 402 rejection
- Network-specific data gaps — token may exist on one chain but return no data if queried against an unsupported chain
