3. Accounts and access

Connecting is free. The first time your assistant uses MarketCheck AI Desk, it opens a secure sign-in page. Signing in creates or links your account at no cost. No admin or developer seat is required.

Once connected, your assistant can run any report and check your balance, invoices, and recent activity on your behalf. You can review the same information, manage your saved payment method, and set up a dealer brand profile in your account area.

Vehicle data coverage is United States market only, keyed off US VINs and ZIP codes.

4. Billing and credits

Account, billing, and support actions (checking your balance, viewing invoices, listing reports, contacting support) are free. Generating a report is pay per use: each run deducts that report's flat fee from your credit balance, and an invoice is recorded for it.

New accounts start with a zero balance, so add credits before your first paid run. Top-ups go through Stripe Checkout. If a run would exceed your balance, your assistant tells you and prompts a top-up first, so you are never charged by surprise.

Prices range from $0.99 to $5.99 per report. Volume top-ups may include bonus credit. See the Terms of Service for the full billing terms.

5. Data, privacy, and support

The server only processes the inputs you (or your assistant on your behalf) provide for a requested report. All traffic runs over encrypted HTTPS. Account details, invoices, and the reports you generate are stored so you can retrieve them later. See the Privacy Policy for what we collect, how it is used, and how long it is kept.

Need help? Email ai@marketcheck.com, or ask your assistant to open a support ticket for you. Billing questions go to billing@marketcheck.com.
