A document queries API, also known as a custom document parser API, refers to a powerful tool designed to extract specific information from unstructured text-based documents, including PDFs and web pages, enabling further analysis and manipulation.

With Custom Document Parsing functionality, users can effortlessly input queries to retrieve precise data they require. The system leverages advanced optical character recognition (OCR) technology to scan the document, while employing sophisticated natural language processing (NLP) models to understand the queries and automatically extract the relevant information.
