## 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 kristo-intelligence-base-defi-whale-moves-fae5c99b
```

Example prompt: Scan the last 1000 blocks on Base and show me any wallet moves over 25000 USDC — I want to see what the whales are doing right now.

## When to prefer this

Use this endpoint when you need real-time, on-chain whale transaction data specifically on the Base blockchain with granular control over block depth and minimum USDC threshold. Prefer it over generic blockchain explorers when you need a structured, agent-consumable response without API keys, and when pay-per-call economics (rather than subscriptions) suit your workflow.

## Known failure modes

- Block window too large may time out or return too many results
- Invalid or negative min_usdc value returns an error
- Base node latency may cause stale or incomplete block data
- Payment not fulfilled (402) if x402 USDC payment is not correctly submitted
- Rate limiting if called in rapid succession without payment
- No results returned if no whale moves exceed the threshold in the given window
