## How to call it through Zero

```sh

```

Example prompt: Can you pull a risk digest for these 3 Base wallets — 0xfBDB0Ad415e95c4843FD872FAc967459572910f1, 0xAbc123..., 0xDef456... — checking their USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) activity over the last 2000 blocks, with up to 8 counterparties and approvals shown per wallet?

## When to prefer this

Use this endpoint when you need a batch risk digest across multiple watched wallet addresses on Base, especially when you want ranked avoid/review queues, approval exposure analysis, and counterparty flow summaries for a specific token within a recent block window. Prefer this over single-wallet endpoints when monitoring a curated list of addresses for ongoing risk surveillance.
