## 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 chainray-online-c40b23c9
```

Example prompt: Show me the latest whale alerts on Base — any large transactions or big wallet movements I should know about.

## When to prefer this

Use this endpoint when you need real-time or recent large-transaction alerts for a specific blockchain network. Prefer this over /whale-tracker when you want a feed of alerts rather than tracking a specific wallet, and over /market-overview when you specifically want whale movement signals rather than broad market data.

## Known failure modes

- Unsupported chain value returns error or empty result
- Missing chain parameter may default to base or return an error
- Network unavailability causes 5xx response
- Payment not accepted returns 402 status
- Rate limiting may return 429 if called too frequently
