Summary: Get all questions on MathOverflow
Operation ID: getQuestions
Auth: none

Returns a list of MathOverflow questions with their metadata including title, tags, author info, scores, view counts, and timestamps. This is the main endpoint for browsing questions — use it to get the latest activity, highest-voted posts, or unanswered questions. Results are paginated and include question body excerpts (not full content). Call this when you want to discover questions rather than retrieve specific ones by ID.

Original spec description

Returns all questions on MathOverflow, with various filtering options

Usage Tips

- Always include `site=mathoverflow` parameter (required) - Use `sort=votes` for highest-rated questions, `sort=creation` for newest - `tagged` parameter filters to questions with specific tags (semicolon-separated for OR, plus-separated for AND) - Default `pagesize` is 30, max is 100 - `filter` parameter can include question bodies and other fields not returned by default - Results include `is_answered` flag — filter client-side if you only want unanswered questions
