## 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 zerion-wallet-portfolio-d410410e
```

Example prompt: Can you pull up the full portfolio breakdown for wallet 0x742d35Cc6634C0532925a3b8D4C9C6A4f5b9E2d1 and tell me its total value across all chains?

## When to prefer this

Choose this endpoint when you need a comprehensive, aggregated portfolio snapshot for a specific wallet across 40+ EVM chains and Solana in a single call. Prefer it over on-chain RPC calls when you want interpreted, human-readable portfolio data without having to aggregate across multiple protocols and chains yourself. Ideal for agents that need total net worth, asset composition, or DeFi position summaries for any wallet address.

## Known failure modes

- Invalid or malformed wallet address returns a 400 or error response
- Non-existent or empty wallet returns data with zero balances
- Rate limiting or quota exhaustion may return 429
- Payment not processed (x402) results in 402 Payment Required
- Network or chain indexing lag may result in stale portfolio data
