## 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 coin-railz-whale-alert-monitor-626de32e -d '<json body>'
```

Example prompt: Show me the latest large on-chain wallet movements for ETH — I want to see any whale transactions above $500K that happened in the last hour so I can gauge whether big players are buying or selling.

## When to prefer this

Choose this endpoint when you need real-time intelligence on large crypto wallet movements to inform trading decisions, detect accumulation or distribution patterns, or monitor specific high-value wallets. Prefer it over general token price endpoints when the signal you care about is behavioral (who is moving funds and how much) rather than price-based.

## Known failure modes

- Missing or invalid wallet/chain parameters return an error
- Payment failure or insufficient USDC balance blocks the call
- Unsupported blockchain network yields no results
- Rate limiting if too many requests in quick succession
- Stale or delayed on-chain data during network congestion
