Metadata for the underlying LE TEEN College ROI API: description, license, attribution, DOI, docs URL, and the list of raw endpoints.

List bachelor's-degree majors (19 broad categories and/or 115 CIP subfields) with lifetime-ROI stats: median/mean lifetime ROI (USD), % of programs that never break even, median break-even age, and AI-exposure band. Returns compact rows sorted by the chosen field. Use the returned slug with get_major for full detail.

Full lifetime-ROI record for one major category or CIP subfield by slug (e.g. 'nursing', 'computer-science', 'philosophy-and-religious-studies'): ROI distribution (p25/median/mean/p75), never-break-even %, break-even age, completion-adjusted and dropout ROI, graduates/programs counts, and AI-exposure detail. Accepts a plain name and will slugify it; use list_majors to discover exact slugs.

Search the 500 largest-coverage U.S. four-year colleges that clear the positive-NPV envelope. Each row: 30-year NPV at resident and non-resident pricing, total cost of attendance, median earnings 10 years after entry, and break-even age. Filter by name substring, state, and control; sorted by resident NPV descending unless overridden. Use the returned slug with get_college.

Full record for one college by slug (e.g. 'university-of-michigan-ann-arbor'): 30-year NPV at resident and non-resident pricing, total cost of attendance both ways, median earnings 10 years after entry, break-even age, IPEDS unitid, and FREOPP program coverage. Accepts a plain name and will slugify it; use search_colleges to discover slugs.

Each U.S. state's best-value four-year colleges at resident pricing, ranked by 30-year NPV (top 15 per state). Pass a state for its full list; omit it for a nationwide summary (every state's top pick).

U.S. public four-year colleges ranked by the out-of-state penalty: how much 30-year NPV a non-resident gives up versus a resident at the same school. Includes both NPVs and both tuition figures per row.
