## 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-gateway-whale-alerts-tool-bbe16d5f -d '<json body>'
```

Example prompt: Can you pull the latest whale alerts right now — I want to see any large crypto transactions that have happened recently so I can spot unusual market activity?

## When to prefer this

Choose this endpoint when you need real-time or near-real-time alerts about large cryptocurrency transactions (whale activity) and are operating in an agent environment that supports x402 micropayment flows. Prefer it over free alternatives when you need reliable, pay-per-call access without API key management, and over general blockchain explorers when you want pre-filtered large-transaction alerts rather than raw transaction data.

## Known failure modes

- Invalid or missing tool parameter returns an error
- Payment failure (insufficient USDC balance) blocks access
- Upstream data source unavailable returns a 5xx or empty response
- Rate limiting if called too frequently
- No recent whale activity results in an empty alerts array
