## 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-by-token-405b2402
```

Example prompt: Pull up the latest whale alerts for the token at 0x6B175474E89094C44Da98b954EedeAC495271d0F — I want to see if any big wallets have been making large moves on it recently.

## When to prefer this

Use this endpoint when you need to detect large on-chain token movements by major holders (whales) for a specific token, and want a paid, low-latency REST API with USDC micropayment via x402 on Base. Prefer this over generic explorers when you need structured alert data programmatically for a single token.

## Known failure modes

- Invalid or unrecognized token address returns an error or empty result
- Token with no recent whale activity returns empty alerts array
- Payment failure via x402 protocol results in 402 response
- Rate limiting or server error returns 500 status
- Malformed token path parameter causes 400 or routing error
