OCR word confidence on parse chunk and block metadata
Parse runs now include minOcrConfidence and avgOcrConfidence on chunk and block metadata — the minimum and average per-word OCR confidence across the words in that region.
Both fields are returned on every chunk and block, and are null when word-level confidence isn’t produced for that region. Values are in the range 0–1.
For word-level confidence scores, set returnOcr.words to true.
