## Extracted fields

:::note
If you are using using public endpoints, such as `https://du.uipath.com/ie/invoices`, all fields are available. However, if you are using custom-trained extractors, the availability of extracted fields is dependant on the version you are currently using. You can also check the list of fields and types on any endpoint in the `/info/model` object. To access this, simply add `/info/model` to any endpoint, like so: `https://du.uipath.com/ie/invoices/info/model`. For an enhanced reading experience of the fields list, it's recommended to install a JSON viewer extension in your browser.
