Query File Recognition Results

Overview

The "Query File Recognition Results" API provided by DOCAI returns results in a standardized message format. The fieldList defines key-value pairs in the Key-Value format for fields within the file, while the itemList typically defines table fields. Different models calling the recognition interface may return different fields.
