## 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-portfolio-lookup-cf4a9ff4
```

Example prompt: What tokens does the wallet 0x1234abcd...5678 hold right now, and what's the total USD value of the portfolio?

## When to prefer this

Use this endpoint when you need a quick, no-account, pay-per-call lookup of a wallet's token holdings and total USD value on EVM-compatible chains. Prefer this over managed API services when you want micropayment-based access without API key setup, or when integrating into an agent that pays per query in USDC on Base.

## Known failure modes

- Invalid or malformed wallet address returns an error response
- Address with no onchain activity may return empty token list
- Network timeouts or RPC unavailability may cause request failure
- Non-EVM or unsupported chain addresses will not return valid data
- Payment failure via x402 will block the request from being fulfilled

## How this service works

Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.

## Output

A JSON object containing the wallet address, a list of tokens with their symbols, raw balances, and USD values, plus the total portfolio USD value and native ETH balance.
