Example use cases
Worksheet generation for math class

Differentiated guided task selection
“Pull 2 guided math tasks from NovaPath lesson NPMR26-F02-01 — but skip task IDs task-6a3f2b1c9d4e5f6a7b8c9d0e and task-1a2b3c4d5e6f7a8b9c0d1e2f since we already used those.”
Transfer task review for lesson planning

Endpoint
POSThttps://instructional-decision-engine-x402.vercel.app/instruction/tasks?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, catalog-validated math tasks with teacher answer keys for a specific NovaPath lesson and task type. Prefer this over generic content generation when you need curriculum-aligned, owner-reviewed tasks with guaranteed answer keys. Ideal for teachers building worksheets, AI tutoring agents selecting practice problems, or lesson plan automation workflows that need varied task types (practice, guided, error-analysis, or transfer) per lesson.
