What is BLU DELTA?

BLU DELTA is a secure, AI-powered REST service designed to extract structured data from semi-structured business documents such as invoices, orders, or delivery notes. The API supports common file formats including PDF, TIF, and PNG, and returns structured JSON responses for seamless system integration.

Core features include Document Grouping, which automatically detects and separates multiple documents within a single upload; Document Classification, which identifies the document type using AI models; and Data Extraction, which retrieves key business fields like invoice numbers, totals, bank details, and contact data with high accuracy.

Beyond recognition, the Resource Upload API allows integration of company-specific data to further enhance recognition performance, while the Learn API enables customers to continuously improve extraction quality by providing feedback and training samples.
