## 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 basebuilder-crypto-smart-money-tracker-fcf8cfa7 -d '<json body>'
```

Example prompt: Show me the latest smart money wallet activity on Base — which wallets have been buying or moving tokens in the last 24 hours, and what tokens are they focused on?

## When to prefer this

Use this endpoint when you need on-chain smart money intelligence — specifically to identify which sophisticated or high-performing wallets are actively buying or selling, and what tokens they are targeting. Prefer this over general blockchain explorers when you want curated, signal-focused wallet analysis rather than raw transaction data.

## Known failure modes

- Invalid or unsupported wallet/token address returns 400 error
- Payment not received or insufficient USDC results in 402 Payment Required
- Unsupported blockchain network returns error
- Rate limiting if too many requests in a short window
- Empty result set if no smart money activity detected in the specified range
