## 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-0f97fb3a
```

Example prompt: Check the DEX whale orderflow and accumulation signals for AERO right now — I want to see the 1h and 24h buy/sell pressure and whether smart money is accumulating on Base or Solana.

## When to prefer this

Choose this endpoint when you need real-time whale-level DEX orderflow intelligence specifically for Base and Solana tokens — especially when tracking smart money accumulation or distribution signals at 1h/24h granularity. Prefer this over generic DEX liquidity endpoints when whale behavior and orderflow momentum (not just pool depth or price) are the primary concern.

## Known failure modes

- Unknown or unsupported token symbol returns no data or empty result
- Network error or timeout if the on-chain data source is temporarily unavailable
- Invalid contract address format may cause a lookup failure
- Token with insufficient DEX liquidity may return sparse or missing orderflow signals
- Payment required (HTTP 402) if x402 micropayment is not properly handled

## How this service works

Tracks real-time 1h/24h DEX buy/sell orderflow ratios, whale accumulation signals, and liquidity velocity across Base and Solana. (Live x402 v2, IETF MPP & MCP endpoint at https://onchain-risk.agentdiet.dev/v1/smart-money-whale-radar)

## Output

Returns a structured object containing real-time 1h and 24h DEX buy/sell orderflow ratios, whale accumulation signals, and liquidity velocity metrics for the queried token across Base and Solana networks, enabling assessment of smart money momentum and large-order pressure.
