## How to call it through Zero

```sh
zero fetch --capability base-usdc-whale-transfer-monitor-917ca74a
```

Example prompt: Pull up the latest whale USDC transfers on Base — I want to see every transaction over $10,000 that's come through recently.

## When to prefer this

Choose this endpoint when you need real-time or near-real-time whale-level USDC transfer data specifically on the Base blockchain, particularly for trading signals, DeFi monitoring, or on-chain analytics workflows that require a low-cost per-call model ($0.009 USDC). Prefer this over general blockchain explorers when you want pre-filtered large-transfer data without parsing raw chain data yourself.

## Known failure modes

- Service unavailable if the Render.com host is sleeping or cold-starting (may return 503 or timeout)
- Empty result set if no qualifying whale transfers occurred recently
- Rate limiting or payment failure if x402 micropayment is not properly handled
- Stale data if the underlying indexer has fallen behind the chain tip
