## How to call it through Zero

```sh
zero fetch --capability hearth-evm-wallet-portfolio-lookup-721ca56e
```

Example prompt: What's the total portfolio value of the wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045, and show me the asset breakdown by chain?

## When to prefer this

Use this endpoint when you need a fast, pay-per-call onchain portfolio snapshot for any EVM wallet address, particularly on Base, without setting up a full indexer or wallet API subscription. Ideal for AI agents that need lightweight, on-demand wallet valuation as part of a larger workflow.

## Known failure modes

- Invalid or malformed EVM address returns an error
- Unsupported chain or address with no indexed holdings may return null fields
- Payment failure via x402 (insufficient USDC balance) results in 402 response before data is returned
- Network or RPC latency may cause timeouts for wallets with many assets

## How this service works

One call: ETH, WETH, USDC and USDT balances for an address across Base, Ethereum, Arbitrum and Optimism, each with a USD value, plus the total USD value and per-chain subtotals. Deterministic, no LLM.

## Output

A JSON object containing the wallet address, total portfolio value in USD, current ETH price in USD, and a per-chain breakdown with each chain's total USD value and a list of assets including symbol, amount held, and USD value.
