## 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 whale-movement-tracker-eth-large-transfer-feed-10fc918e
```

Example prompt: Pull the latest large ETH whale transfers and tell me which entities — exchanges, funds, or known wallets — are sending or receiving big amounts right now.

## When to prefer this

Use this endpoint when you need real-time or near-real-time intelligence on large Ethereum transfers enriched with entity labels, especially for detecting smart money flows, exchange inflows/outflows, or coordinated whale activity. Prefer this over generic block explorers when you need pre-labeled sender/receiver classification rather than raw address data.

## Known failure modes

- No large transfers detected in the recent window — returns empty list
- Rate limit or payment failure — 402 payment required if x402 header is missing or insufficient
- Service unavailable — upstream node indexer down, returns 503
- Stale data — if the indexer lags, returned transfers may not reflect the last few minutes

## How this service works

Recent large ETH transfers with sender/receiver labels and entity classification. AI agent API for whale movement detection and flow analysis

## Output

A list of recent large ETH on-chain transfers, each including sender and receiver wallet addresses with human-readable labels (e.g. 'Binance', 'Jump Trading'), entity type classification (exchange, fund, unknown, etc.), transfer amounts in ETH, and timestamps — enabling analysis of where large capital is flowing on Ethereum.
