## 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 lenscrypt-whale-alerts-token-whale-activity-feed-ef5c8b76
```

Example prompt: Pull the latest whale alerts for the token at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 — I want to see which big wallets have been making large moves recently.

## When to prefer this

Use this endpoint when you need real-time or near-real-time intelligence on large on-chain token movements by major holders (whales). Prefer it over generic blockchain explorers when you want pre-filtered, high-value transaction signals without manually parsing raw block data. Best suited for trading agents, DeFi risk monitors, and research tools that need whale activity as a signal for price action or market sentiment.

## Known failure modes

- Invalid or unrecognized token address/symbol returns an error or empty result
- Token not tracked by the system returns no whale alert data
- Rate limiting or payment failure (x402) blocks the response
- Network or upstream data provider outage yields a 500 error
- Malformed token parameter in URL path returns a 400 bad request
