## 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-base-solana-dex-whale-orderflow-accumulation-7aebbabc
```

Example prompt: Can you scan the current DEX whale orderflow for AERO — I want to see the 1h and 24h buy/sell ratios and whether whales are accumulating or distributing right now?

## When to prefer this

Choose this endpoint when you need real-time on-chain DEX intelligence specifically for Base or Solana tokens, including whale wallet accumulation signals and orderflow momentum. Prefer this over generic price APIs when the goal is to detect smart money behavior, buy/sell imbalance, or liquidity shifts rather than just spot price. Ideal for pre-trade analysis, momentum screening, or building DeFi trading agents that react to whale activity.

## Known failure modes

- Unknown or unsupported token symbol returns empty or error response
- Contract address for unsupported chain returns no data
- Missing required 'symbol' parameter results in 400 validation error
- Payment not fulfilled triggers HTTP 402 response requiring x402 USDC payment
- Token with insufficient DEX liquidity may return sparse or null signals
- Rate limiting or upstream data lag may cause stale or delayed results
