Questions

What can the AI do in RealEstateAPI?

The AI can search US properties, also with a plain-English question, autocomplete and verify addresses, and read property details, valuations, comparable sales and liens. It can search and read MLS listings, find contact details for an owner, look up a company that owns property, and check your API key's scopes and usage.

Does the AI see my RealEstateAPI credentials?

No. Your RealEstateAPI credentials 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, for example property search and details without skip tracing. Any tool can be set to require your approval before it runs, and 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 RealEstateAPI account.

Which data can I query?

That depends on your RealEstateAPI plan. Property, MLS, skip trace and valuation data are separate datasets. Ask the AI to check your API key, and it reads the available scopes, rate limits and usage for the key you connected.
