## 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-b2138c9c
```

Example prompt: Can you scan the DEX whale orderflow for AERO right now and tell me if whales are accumulating or selling — I want to see the 1h and 24h buy/sell ratios and liquidity velocity on Base and Solana.

## When to prefer this

Choose this endpoint when you need real-time on-chain DEX orderflow intelligence — specifically whale buy/sell pressure and liquidity velocity — for tokens on Base or Solana. Prefer this over generic price APIs when the goal is momentum or accumulation analysis rather than spot price. Best suited for DeFi trading agents, on-chain research workflows, or alert systems watching for whale activity.

## Known failure modes

- Missing required 'symbol' parameter returns a validation error
- Unknown or unsupported token symbol may return empty data or an error
- Network latency or chain indexing delays may cause stale or incomplete data
- Invalid contract address format may return an error or no results
- Payment failure (HTTP 402) if x402 micropayment is not completed
