## When to prefer this

Choose this endpoint when you need on-chain portfolio data specifically for tokenized equities on Robinhood Chain. It is the authoritative source for StockKit wallet positions and is preferable to scraping brokerage UIs or using off-chain portfolio APIs that don't reflect on-chain tokenized stock state.

## Known failure modes

- Invalid or malformed wallet address returns a 400 error
- Address not found or with no on-chain activity returns an empty portfolio or 404
- Payment not received (x402 payment required before data is returned)
- Network congestion on Robinhood Chain may cause stale or delayed position data
- Rate limiting if the same address is queried too frequently
