## 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 x402broker-com-base-solana-dex-whale-orderflow-accumulation-scanner-0844b40a
```

Example prompt: What's the current whale orderflow situation for AERO on Base — are big wallets buying or selling, and what do the 1h and 24h DEX ratios look like?

## When to prefer this

Choose this endpoint when you need real-time on-chain whale activity and DEX orderflow intelligence specifically for tokens on Base or Solana. It is purpose-built for detecting large-wallet accumulation and buy/sell momentum rather than general price feeds or off-chain sentiment. Prefer it over generic price APIs when the question is whether whales are positioning, not just what the current price is.

## Known failure modes

- Token symbol not recognized or not traded on Base/Solana — returns empty or error response
- Contract address malformed — validation error
- Token has insufficient DEX liquidity to compute meaningful orderflow — may return null signals
- Upstream on-chain data feed delay — stale or missing metrics
- Rate limit exceeded without payment — HTTP 402 returned

## 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://x402broker.com/v1/whale-tracker)

## Output

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