How this service works
Retrieve an existing two-item entry or exit check with separate answer guidance and next steps. No learner records required; not a standardized diagnostic. Owner review attested.
Output
Returns a two-item instructional check (entry or exit) for the specified lesson, including the check questions, separate answer guidance, and recommended next steps. No learner records are created or stored.
Example use cases
Pre-lesson readiness check for teacher
“Get me the entry check for NovaPath lesson NPMR26-F05-02 so I can see what two questions students should answer before we start, along with the answer guidance.”
Post-lesson exit check with next steps
“Fetch the exit check for lesson NPMR26-F07-04 — I want to see the two check items and what next steps are recommended based on student answers.”
Filtered check excluding used tasks
“Retrieve the entry check for lesson NPMR26-F02-03 but exclude task IDs task-5f3a2b1c4d9e8f7a6b0c1d2e and task-1a2b3c4d5e6f7a8b9c0d1e2f from the results.”
Technical details
Endpoint
POSThttps://instructional-decision-engine-x402.vercel.app/instruction/checks?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to retrieve a pre-built two-item instructional check (entry or exit) for a specific NovaPath lesson, complete with answer guidance and next steps, without needing to create new content or store learner records. Prefer this over generative assessment endpoints when you want consistent, authored check items from the NovaPath catalog.
Side effects
- Invalid lessonId pattern returns validation error
- Unsupported lessonId not found in catalog returns not-found error
- Stage must be exactly 'entry' or 'exit' — other values rejected
- excludeTaskIds exceeding 50 items or with invalid pattern returns schema error
- Payment not received or insufficient USDC results in 402 Payment Required
