Retrieve the contact api can't retrieve some fields, like website, social accounts, job title

I add a contact in Infusionsoft app including these fields Job title, Anniversary, Birthday, Fax Numbers, Preferred Name, Spouse Name, Notes, Social Accounts, Website.

Then I retrieve the concat by Get https://api.infusionsoft.com/crm/rest/v1/contacts/{id} by postman, but the fields (Job title, Anniversary, Birthday, Fax Numbers, Preferred Name, Spouse Name, Notes, Social Accounts, Website) can’t be retrieved in response.
How to retrieve these fields by postman?

My account is not a paid account.

The model shown on the documentation page should be the object you are returned, assuming there is data on the record to see. You can try it via the interactive documentation to verify.
