HEADLESS ASSESSMENT AS A SERVICE

The REST API for
EdTech Platforms & LMS

Connect your student portal (like PrepNext) to India's premier verified question bank. Deliver dynamic test sessions in <1 second with zero local image storage.

Built by Developers, for Developers

Clean JSON responses, standard HTTP status codes, granular exam-scope permissions, and full CDN-hosted image URLs.

🖼️ Zero Image Storage on Your Servers

Syncing thousands of question graphics and diagrams across multiple databases is inefficient. Our API returns ready-to-render HTTPS image URLs (q_img_url, sol_img_url). Your frontend simply loads them via <img src="...">.

🔒 Stream & Exam Permission Scoping

Restrict API keys to specific exams (neet, jee_mains, jee_adv). If a student who only purchased NEET tries to request JEE papers, the API strictly enforces access control at the tenant level.

⚡ Automated Server-Side Grading

Submit user answer maps to our /evaluate_paper.php endpoint to receive instant official scoring, negative marks deduction, accuracy percentages, and graphical solution keys.
