## How to call it through Zero

```sh
zero fetch --capability zerion-wallet-portfolio-chart-b9e0e6b7
```

Example prompt: Can you pull the 3-month portfolio value chart for wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44e using Zerion so I can see how its total holdings have trended?

## When to prefer this

Use this endpoint when you need historical portfolio value chart data for a specific wallet address across multiple chains. Prefer it over generic block explorers when you want interpreted, aggregated multi-chain portfolio value time-series rather than raw transaction lists. Ideal for agents building performance dashboards, tracking wallet growth, or comparing portfolio trajectories over defined time windows.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Unsupported chart_period value outside the allowed enum returns a validation error
- Wallet with no history for the requested period may return empty data attributes
- Payment failure (x402) if USDC balance is insufficient blocks the request
- Rate limiting or authentication errors if x402 payment is not correctly handled

## How this service works

Interpreted wallet data for more than 40 chains and Solana: portfolios, DeFi positions, PnL, transactions and NFTs. REST for apps, x402 pay-per-call for agents.

## Output

A JSON object containing chart data for the wallet's total portfolio value over the requested time period, including a data object with resource ID, resource type, and attributes (time-series value points), plus a self link for the query.
