Technical details
Endpoint
POSThttps://instructional-decision-engine-x402.vercel.app/instruction/worked-example?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a specific, pre-authored math worked example with structured explanation steps and an attested model answer from the NovaPath catalog — particularly when the lesson ID is already known from the /instruction/catalog. This is preferable over generative math solvers when you need a curated, owner-reviewed canonical solution rather than an on-the-fly AI-generated answer.
Side effects
- Invalid lessonId format (must match ^NPMR26-F[0-9]{2}-[0-9]{2}$) returns a validation error
- Requested lessonId not found in catalog returns a not-found error
- Lesson not currently available or outside catalog scope causes availability validation failure before payment is processed
- Payment failure via x402 protocol prevents content delivery
- Service downtime on Vercel hosting causes timeout or 5xx error
