## 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 agentfund-on-chain-portfolio-usd-valued-c6aea897 -d '<json body>'
```

Example prompt: What's the current USD-valued on-chain portfolio for wallet address 0x1234abcd... on Base? I want to see all token holdings and their values.

## When to prefer this

Use this endpoint when you need a quick, USD-denominated snapshot of a Base wallet's on-chain portfolio. Prefer it over generic blockchain explorers when you need structured, JSON-formatted token valuations ready for downstream processing or reporting by an AI agent.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Wallet address not on Base network may return empty or error
- Network/RPC issues may cause timeouts or stale data
- Payment failure via x402 protocol results in 402 response before data is returned
