Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 alpha-palmvox-com-efb11273
```

Example prompt: What are the crypto whales doing right now — are they accumulating or dumping BTC, ETH, and SOL, and what's the overall market bias?

## When to prefer this

Use this endpoint when you need a quick, pre-aggregated snapshot of whale behavior across BTC, ETH, and SOL without performing raw on-chain analysis yourself. Ideal for agents that need to factor large-wallet sentiment into trading decisions, portfolio adjustments, or market summaries. Prefer over raw blockchain RPC calls when speed and simplicity matter more than exhaustive transaction data.

## Known failure modes

- Stale data if scan cycle has not recently run — lastUpdated timestamp may be minutes old
- LOW confidence signals indicate insufficient whale data to draw strong conclusions
- Empty whales array if no significant movements detected in current scan cycle
- HTTP 402 Payment Required if x402 payment header is missing or insufficient
- Network timeout if upstream on-chain data provider is delayed

## How this service works

Whale activity summary — large movements detected across BTC, ETH, SOL. Includes direction (accumulating/distributing), estimated size, and market impact. Updated every scan cycle.

## Output

Returns an array of whale activity records per token (SOL, ETH, etc.), each with current price, 24h change, direction (accumulating/distributing/neutral), confidence level (LOW/MEDIUM/HIGH), and market impact descriptor. Also includes an overall marketBias string, a lastUpdated ISO timestamp, and links to related endpoints.
