Example prompt: Pull up my Otto AI Safe portfolio for wallet 0x742d35Cc6634C0532925a3b844Bc9e7595f42bE4 — I want to see my total value, idle cash, and any Aave or Morpho yield positions across all chains.

## When to prefer this

Use this endpoint when you need a unified multi-chain DeFi portfolio view specifically for Otto AI Safe accounts, including both spot token balances and yield protocol positions (Aave V3, Morpho) in a single call. Prefer this over generic balance APIs when the user has an Otto AI Safe and wants actionable DeFi recommendations alongside their balances.

## Known failure modes

- Missing or invalid userId (non-0x address format) returns a validation error
- Wallet address with no associated Otto AI Safe returns empty safeAddresses array and zero balances
- Chain RPC timeouts may result in partial data for some chains
- Invalid or malformed EVM address returns an error response
- Rate limiting or payment failure returns a 402 Payment Required
