Stack Overflow & Stack Exchange Scraper

Search questions — and optionally their full answers — across Stack Overflow and any Stack Exchange site, by keyword, tags, votes or recency. Includes question/answer bodies, scores and accepted flags. Free API (add a free key for 10,000 requests/day).

Ideal for LLM training datasets, technical research, dev-trend analysis and content pipelines — clean, structured Q&A with the signals you filter on.

What you get

Questions — one row per question:

• questionId, title, link, score, viewCount
• answerCount, isAnswered, acceptedAnswerId
• tags, owner, body (HTML), createdAt, lastActivity

Answers (when includeAnswers: true) — nested answers[], each with answerId, score, isAccepted, owner, body, createdAt, link
