## 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 x402-chain-intel-whale-move-alerts-b4762e64 -d '<json body>'
```

Example prompt: Alert me whenever a whale moves more than 500,000 USDC on Ethereum — I need the sender address, receiver address, and transaction hash so my trading bot can react immediately.

## When to prefer this

Choose this endpoint when you need real-time on-chain whale transaction detection for trading bots or alert systems, especially when you want to react to large token movements as a trading signal. Prefer this over generic blockchain explorers when you need structured, machine-readable output optimized for automated consumption at $0.20 USDC per call.

## Known failure modes

- No whale activity found matching threshold in recent blocks — returns empty result set
- Invalid or unsupported token/contract address — returns 400 error
- Unsupported chain identifier — returns validation error
- Payment not received or insufficient USDC — returns 402 payment required
- RPC node unavailability causing data gaps — may return partial or delayed results
