Frequently asked questions

Can I build the Alpaca integration with AI coding tools?

Yes. Connect Trade publishes a complete OpenAPI specification and llms.txt documentation. Load the reference files into Claude Code, Cursor, Codex, or any AI coding agent, copy a starter prompt, and generate a working Alpaca integration in a single session. See Build with AI in the Connect Trade docs.

Does Connect Trade support AI agent trading on Alpaca?

Yes. The Connect Trade MCP server gives AI agents structured, permissioned access to Alpaca accounts along with the rest of the Connect Trade broker network. Agents read portfolios, analyze positions, and place trades across equities, options, and crypto through a single server-side integration, with automatic execution or manual approval per order.

How do users connect their Alpaca accounts?

Through OAuth. Users authorize access with a click-through flow, and the connection is live. Connect Trade handles the authentication end to end.

What can I build on Alpaca with Connect Trade?

Trading applications, portfolio and analytics platforms, systematic trading tools, and AI agents. Alpaca supports paper trading through Connect Trade, so you can build and test a full integration against simulated accounts before connecting live money, across equities, options, and crypto.

Which asset classes does Connect Trade support on Alpaca?

Equities, options, and crypto. Connect Trade supports live trading across all three on connected Alpaca accounts, with single-leg and multi-leg options, real-time market data, and paper trading.

Is the Connect Trade Alpaca integration compliance approved?

Yes. Every Connect Trade integration is compliance approved and built on the broker's official API. Connect Trade uses sanctioned APIs across the entire network.

Does Connect Trade support brokers other than Alpaca?

Yes. Connect Trade supports more than 20 compliance-approved brokers through one normalized API. The Alpaca integration uses the same request and response model as every other broker in the network, so a single integration extends across all of them.
