## 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-180220c9
```

Example prompt: Can you check the whale orderflow and smart money accumulation signals for AERO right now — I want to see the 1h and 24h buy/sell ratios and whether whales are accumulating or distributing on Base and Solana DEXes?

## When to prefer this

Choose this endpoint when you need real-time on-chain whale behavior and DEX orderflow intelligence specifically for tokens on Base or Solana — particularly when you want smart money accumulation signals and buy/sell pressure ratios rather than just price data. Prefer this over generic price feeds when the question is 'are whales buying or selling?' rather than 'what is the current price?'

## Known failure modes

- Unknown or unsupported token symbol returns empty or error response
- Contract address for unsupported chain returns no data
- Network latency or DEX data feed outage causes stale or missing orderflow data
- Highly illiquid tokens may have insufficient orderflow data for meaningful signals
- Missing required 'symbol' parameter returns validation error
