## 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 hn-pulse-agentdiet-dev-base-solana-dex-whale-orderflow-accumulation-aee6a216
```

Example prompt: Can you check the whale orderflow and accumulation signals for AERO right now — specifically the 1h and 24h buy/sell ratios and whether smart money is accumulating on Base or Solana DEXes?

## When to prefer this

Use this endpoint when you need real-time on-chain whale intelligence specifically for tokens trading on Base or Solana DEXes, particularly when you want buy/sell orderflow ratios across both 1h and 24h windows alongside accumulation signals. Prefer this over general price APIs when the goal is detecting smart money positioning or liquidity momentum rather than just price.

## Known failure modes

- Missing or invalid token symbol returns an error — symbol must be non-empty
- Unknown or unsupported token may return empty or null signals
- Network connectivity issues may cause timeouts on real-time data fetch
- Payment failure (HTTP 402) if x402 micropayment is not properly handled
- Token contract address typo results in no matching data

## 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://hn-pulse.agentdiet.dev/v1/smart-money-whale-radar)

## Output

Returns structured data including 1-hour and 24-hour DEX buy/sell orderflow ratios, whale accumulation signals (bullish/bearish/neutral), and liquidity velocity metrics for the queried token across Base and Solana networks.
