Aspose.OMR Cloud REST API

Perform optical mark recognition and generate OMR-ready forms from a command line or Bash scripts without downloading and installing any software.

Aspose.OMR Cloud is an easy-to-use and versatile online service for designing, rendering and recognizing hand-filled answer sheets, surveys, questionnaires, tests, insurance claims, and similar forms. With it, you can quickly develop applications for optical mark recognition (OMR) that require minimal resources on the client side - all the work is performed by remote services.

You do not need to install any software to use our OMR cloud services. Just use cURL commands or combine them into scripts for complex tasks. You can also use third party REST API tools like Postman.

Quick start

OMR Cloud API can be used from a command line, Bash script, Postman, or a web browser without installing any software or writing code in any of the programming languages. Simply create an HTTP request with required parameters and get the result.

Wide range of applications

Optical Mark Recognition (OMR) technology has many applications and can greatly simplify almost any part of your life when you need to collect and analyze manually filled data. It fully automates the process, allowing hundreds of sheets per minute to be recognized with nearly 100% accuracy, and saves the results directly to a database for further aggregation and analysis. Applications include but are not limited to:

Education: answer sheets, tests, quizzes, SAT forms, and many more.
Questionnaires: customer satisfaction surveys, feedback forms, orders, meal preferences.
Applications: insurance claims, financial applications, border entry forms.
And many more.

Create forms without design tools

Our API supports the complete OMR workflow - from designing a form to recognizing its scanned hardcopies. It offers highly flexible JSON and text markups with 20 layout and content elements that can be combined with each other to produce forms of any layout can complexity.

Forms are generated in most popular graphic formats, as well as PDF documents, which allows you to print them on a regular printer or on high-quality typographical equipment.

No specialized equipment required

You no longer need specialized scanners, paper, and other “hardware” solutions. Advanced image analysis and artificial intelligence techniques made it possible to use a regular pen and paper, common office copier, or even a smartphone camera instead of dedicated devices, without affecting recognition accuracy and confidence in the result. Recognition accuracy of our OMR API competes on par with traditional hardware-based systems at a much lower cost.

Unlimited possibilities with Aspose Cloud solutions

An account in Aspose Cloud grants you access to the full range of our cloud APIs. You can read write-in fields with OCR, build document and presentations from aggregated recognition results, analyze survey data with pivot tables. All tasks are performed in the same way, which significantly speeds up development, reduces learning and maintenance costs, even for the most advanced business solution.
