## 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 onchain-risk-agentdiet-dev-base-solana-dex-whale-orderflow-4a55599a
```

Example prompt: Are whales accumulating AERO right now? Pull the real-time 1h and 24h DEX buy/sell orderflow ratios and whale accumulation signals for AERO across Base and Solana.

## When to prefer this

Choose this endpoint when you need real-time on-chain whale sentiment and orderflow momentum for a specific token on Base or Solana — particularly when making pre-trade decisions, detecting smart money accumulation, or monitoring for sudden large-wallet activity. Prefer this over generic price APIs when you specifically need buy/sell pressure ratios and whale-level signals rather than just price or volume.

## Known failure modes

- Unknown or unlisted token symbol returns empty or error response
- Contract address not found on Base or Solana returns no data
- Network outage or DEX data feed delay causes stale or missing metrics
- Malformed symbol parameter triggers validation error
- Rate limiting or payment failure (HTTP 402) blocks the request
