Why line_1 column in https://api.easyship.com/2022-10/shipments api is too short?

Why is the shipment on dashboard UI able to accept Address Line 1 larger than 35 characters, for example 7404-7428 Singer Landing NW, Edmonton, AB T6R 3S2, so why when I use this API line_1 is limited to 35 characters and other relation API as get rate...etc. What's the problem here? I want to add one more field such as notes to save an address that is too long such as: 7404-7428 Singer Landing NW, Edmonton, AB T6R 3S2. This is an address where I don't know what state or city is. That's why I want an extra field to record the customer's address.
