## 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 polymarket-odds-agentdiet-dev-base-solana-dex-whale-orderflow-fdc1c4d3
```

Example prompt: Check the DEX whale orderflow scanner for AERO — I want to see the 1h and 24h buy/sell ratios and whether big wallets are accumulating right now on Base or Solana.

## When to prefer this

Choose this endpoint when you need real-time, on-chain DEX whale activity specifically on Base or Solana — particularly buy/sell orderflow imbalance and large-wallet accumulation signals. Prefer it over generic price APIs when the goal is detecting institutional or whale-level momentum rather than just price or volume. Best suited for pre-trade research, DeFi strategy agents, or on-chain sentiment monitoring workflows.

## Known failure modes

- Unknown or unsupported token symbol returns an error or empty result
- Contract address on an unsupported chain yields no data
- Rate limiting or payment failure (HTTP 402) if x402 micropayment not properly handled
- Stale or unavailable on-chain data source may result in degraded or null signals
- Very low-liquidity tokens may return incomplete orderflow data
