## 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 wallet-token-portfolio-75981f21
```

Example prompt: Can you pull up the full token portfolio for Base address 0x1234...abcd, with live USD values for all the ETH, stablecoins, and cbETH it holds?

## When to prefer this

Choose this endpoint when you need a fast, consolidated view of the most common Base network tokens (ETH, WETH, USDC, USDbC, DAI, cbETH) with live USD valuations for any wallet, without having to aggregate multiple on-chain RPC calls or price feeds yourself. It is ideal for DeFi dashboards, pre-transaction liquidity checks, and treasury monitoring where only the major liquid assets matter. If you need ERC-20 approvals, transaction history, or tokens beyond the supported set, consider sibling endpoints like Agent Wallet Audit.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Address with no supported token holdings returns an empty result set
- DexScreener price feed unavailable may cause missing or stale USD values
- Rate limiting or payment failure (x402) results in a 402 Payment Required response
- Non-Base-network addresses may return incorrect or empty results

## How this service works

Returns native ETH plus WETH, USDC, USDbC, DAI, cbETH balances for any Base address, enriched with live USD values via DexScreener. Only non-zero holdings are returned.

## Output

A list of non-zero token balances for the queried Base address, covering native ETH, WETH, USDC, USDbC, DAI, and cbETH, each annotated with a live USD value sourced from DexScreener. Zero-balance tokens are omitted from the response.
