## 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-b8cf275d
```

Example prompt: Check the real-time DEX whale orderflow and accumulation signals for SOL right now — I want to see the 1h and 24h buy/sell ratios and whether big wallets are accumulating.

## 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, particularly when you want 1h/24h buy/sell ratio breakdowns and large-wallet accumulation signals rather than price feeds or CEX order book data.

## Known failure modes

- Missing or invalid symbol parameter returns an error
- Unknown or unsupported token symbol returns empty or null data
- Network or upstream DEX data feed latency may cause stale results
- Contract address for low-liquidity tokens may return insufficient data
- Payment failure (402) if x402 micropayment is not properly handled
