Progression

Browse available lessons

Browse available lessons for a learning app. Use this to find lesson IDs before creating a custom hole-filling course.

Getting started: Query with just app (no filters) to discover available subjects and grade levels. The response includes subject and gradeLevel on each lesson — use those exact values to narrow down.

Lesson ID formats vary by app:

MobyMax: mobymax_reading_1654_g3
Freckle: UUIDs or standard codes (FR-CCSS-2-W.6.3.d)
Edia: dotted paths (middle_school.factors and multiples.factor_expressions)
Lalilo: numeric IDs (168, 532)
VocabLoco: structured IDs (vocabloco_g1171_long_a_words)
Anton: path-style IDs (c-nateng-k/yx4m8g)

Grade values: Accepts PK, K, 1–12. Canonical values -1 and 0 are also accepted.

Pagination: Default 100 lessons per page, max 500. Use page and limit to paginate. Response includes pagination.total and pagination.totalPages.
