## 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 ragradar-whale-alerts-74b2da89
```

Example prompt: Show me the latest whale alerts on Base — any large wallet movements or big token transfers happening right now.

## When to prefer this

Choose this endpoint when you need real-time on-chain whale activity monitoring across Base, Arbitrum, or Solana — specifically for detecting large wallet movements or big token transfers. Prefer this over generic blockchain explorers when you need structured, agent-ready data with micropayment access via x402.

## Known failure modes

- Missing or invalid properties parameter returns malformed response
- Payment not included results in HTTP 402 requiring x402 micropayment of $0.01 USDC
- No whale activity in recent timeframe may return empty alert list
- Unsupported chain filter returns no results or error
- Rate limiting if called too frequently without valid payment
