## 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-203c5a94
```

Example prompt: Can you check the current DEX whale orderflow and accumulation signals for SOL — I want to see the 1h and 24h buy/sell ratios and whether big wallets are actively accumulating right now?

## When to prefer this

Choose this endpoint when you need real-time on-chain DEX orderflow intelligence specifically for Base and Solana tokens, especially whale-level accumulation signals and buy/sell momentum — superior to generic price feeds or CEX data when you want to detect smart-money positioning before price moves.

## Known failure modes

- Unknown or unsupported token symbol returns an error or empty result
- Contract address on unsupported chain may return no data
- Rate limiting or payment failure (HTTP 402) if USDC micropayment is not processed
- Stale data during periods of low DEX activity or chain congestion
- Ambiguous symbol (e.g. multiple tokens with same ticker) may return data for wrong token
