Properties

Name Type Description
id string Unique identifier for the prediction.
label string Label name corresponding to a field or table header configured in the model.
label_id string Unique identifier for the label as defined in the model.
type string Indicates whether the prediction is a field or a table header.
xmin number Left edge of the bounding box.
ymin number Top edge of the bounding box.
xmax number Right edge of the bounding box.
ymax number Bottom edge of the bounding box.
score number Confidence score from the model.
ocr_text string Predicted value associated with the label.
status string Status of the predicted label (typically 'correctly_predicted').
validation_status string Present and equal to 'failed' when an approval rule did not pass; absent on success.
validation_message string Reason a label-level validation rule failed.
page_no integer Zero-indexed page number in the document.
cells array Cell predictions when this prediction is a table.
