## 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 api-vibe-airforce-2f43f0ed -d '<json body>'

Example prompt: What tokens are smart money wallets currently holding according to Nansen? I want to see their latest on-chain positions — filter for wallets holding ETH if possible.

## When to prefer this

Use this endpoint when you need current on-chain token holdings specifically attributed to Nansen-classified smart money wallets, and you want institutional-grade wallet intelligence rather than raw blockchain data. Prefer this over generic balance lookups when the goal is to understand what sophisticated or successful traders are holding right now.

## Known failure modes

- Invalid or unsupported payload parameters return an error
- Nansen API unavailable causes 502/503 response
- Missing required payload fields results in a 400 bad request
- Payment not received or insufficient USDC causes 402 payment required
- Rate limiting on the underlying Nansen data source
