## 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 three-ws-robinhood-portfolio-lookup-b85fac87
```

Example prompt: What tokenized stock positions does the wallet 0x9701fb0aDe1E269c8f64Ec0C7b3cfADB31A13A52 hold through Robinhood on-chain, and what's the total USD value of the portfolio?

## When to prefer this

Use this endpoint when you need on-chain, real-time USD valuation of Robinhood tokenized stock positions held in an EVM wallet, sourced directly from Chainlink price feeds via multicall — particularly useful for DeFi collateral checks, portfolio aggregators, or any agent workflow requiring trustless equity balance data without relying on Robinhood's centralized API.

## Known failure modes

- Invalid or malformed EVM address returns an error
- Wallet holds no Robinhood tokenized positions — returns empty positions array and totalValueUsd of 0
- Chainlink oracle price unavailable — navPriceUsd and valueUsd may be null for affected positions
- Network or RPC errors cause timeout or 5xx response
- Payment of 0.002 USDC not provided — endpoint returns 402 Payment Required

## How this service works

Make a 3D AI agent from a selfie in 60 seconds. Drop one HTML tag to embed it on any website. Agents think on IBM watsonx.ai (Granite); optionally charge per chat with built-in micropayments.

## Output

Returns a JSON object with the wallet owner address, a timestamp (asOf), the data source (Chainlink on-chain multicall), an array of tokenized equity positions (each with name, symbol, on-chain contract address, raw balance, share count, NAV price in USD, UI multiplier, and USD value), the total count of positions, and the total portfolio value in USD.
