Questions

What can the AI do in Alpaca?

The AI can read your account, positions, orders, account activities, portfolio history, assets, option contracts, watchlists and the market clock and calendar. It can cancel open orders, create and update watchlists and remove a symbol from a watchlist. The Alpaca tools in HeyMyApps do not place new orders.

Does the AI see my Alpaca API keys?

No. Your Alpaca API key ID and secret key are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start read-only. Cancelling an order cannot be undone, and it can require your approval before it runs. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Alpaca account.

Can I use a paper trading account?

Yes. Generate API keys for your paper account in the Alpaca dashboard and use the address https://paper-api.alpaca.markets. Paper and live accounts have separate keys, so you can try everything on paper before you connect a live account.
