## 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 x402broker-com-base-solana-dex-whale-orderflow-accumulation-scanner-83fd0e1a
```

Example prompt: Can you scan AERO for whale orderflow right now — show me the 1h and 24h buy/sell ratios and whether whales are accumulating or distributing on Base DEX?

## When to prefer this

Choose this endpoint when you need real-time on-chain whale orderflow intelligence specifically for tokens trading on Base or Solana DEXes. It is best when the user wants to detect accumulation/distribution patterns, momentum signals, or buy/sell pressure from large wallets before making a trade or investment decision. Prefer this over general price APIs when smart-money behavior and orderflow ratios — not just price — are the key decision input.

## Known failure modes

- Unknown or unsupported token symbol returns empty or error response
- Contract address on unsupported chain yields no data
- Rate-limit or payment failure (HTTP 402) if x402 payment is not processed
- Network latency may cause stale or missing real-time data during high congestion
- Newly listed tokens with insufficient DEX liquidity may return incomplete signals
