## 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 vextorium-tokenized-stock-etf-portfolio-lookup-solana-8c5c9e40 -d '<json body>'
```

Example prompt: Can you check which tokenized stocks and ETFs — xStocks and Ondo tokens — are held by Solana wallet HcjfmZLgWRZzwj4deEiS7pewc4KBYSw39mW5nTyt3pz2 and tell me the total USD value of the portfolio?

## When to prefer this

Use this endpoint when you need to audit or display a Solana wallet's exposure to tokenized real-world equity assets (xStocks, Ondo) with current USD valuations. Prefer it over generic Solana token balance endpoints because it filters to only officially verified tokenized stock/ETF tokens and enriches results with DEX pricing. Best suited for portfolio dashboards, compliance checks, or rebalancing workflows involving RWA tokens on Solana.

## Known failure modes

- Invalid or malformed Solana wallet address returns empty positions or error
- Wallet holds no verified tokenized stock/ETF tokens — returns posiciones:[] and valor_total_usd:0
- Token price temporarily unavailable from Jupiter DEX — position value may be null or stale
- Registry may not include newly launched tokenized assets not yet in the official verified list
- Network or upstream Jupiter pricing latency causing slow or failed price resolution

## How this service works

Which verified tokenized stocks and ETFs (xStocks, Ondo) a Solana wallet holds, with amount, token price and USD value; only official tokens from the verified registry count.

## Output

A JSON object containing the queried wallet address, an array of positions (each with token name/symbol, amount held, token price in USD sourced from Jupiter DEX, and position USD value), the total portfolio value in USD across all verified tokenized stock/ETF tokens, and a note clarifying that prices are DEX-based (Jupiter) and may deviate from underlying equity prices. Only tokens in the official xStocks/Ondo verified registry are counted.
