Your account, your control
What the connection can and cannot do
You sign in on arstdata.com
The assistant never sees your password. It receives a token that expires after an hour and renews only while you keep the connection.
Valuations only
The connection can value cars, show coverage and read your balance. It cannot open your portfolio, invoices, reports or API keys.
Same credits, same rules
Each valuation is charged exactly like on the web and the API, from the same balance. Invalid input is not charged.
Disconnect any time
The connection appears on your API keys page as “AI assistant · …”. Revoke it there and the assistant loses access at once.
What you type goes to your assistant
Your conversation is processed by the AI provider you chose, under its own terms. ARST Data receives only the vehicle data of each valuation.
Free to start
Create your account: 5 free valuations
Then connect the assistant you already use.
