Document Ingestion API can be used to detect signatures and return their bounding boxes. Signature detection incurs additional costs, so please refer to the pricing page for more details.

​
Detecting Signatures

Bounding boxes of signatures can be detected by setting signature_detection to true in the parse_options JSON object when calling the parse API. 
from tensorlake.documentai import (
    DocumentAI,
    ParsingOptions,
)

doc_ai = DocumentAI(api_key="YOUR_API_KEY")

parsing_options = ParsingOptions(
    signature_detection=True,
)

parse_id = doc_ai.read(
    file_id="file_XXX",  # Replace with your file ID or URL
    parsing_options=parsing_options,
)

​
Response

The bounding boxes of signatures are present in the Document object returned by the parse API. 
parsed_result = doc_ai.wait_for_completion(parse_id=parse_id)
# There is a signature on page 10 of this document
signature_fragment result.outputs.document.pages[10].page_fragments[0]
# PageFragment(fragment_type=<PageFragmentType.SIGNATURE: 'signature'>, content=Text(content='Signature detected'), reading_order=-1, page_number=None, bbox={'x1': 79.0, 'x2': 200.0, 'y1': 812.0, 'y2': 855.0})
