QuizBase vs QuizAPI — general trivia at scale vs programming-mostly developer quizzes

QuizAPI is a developer-focused quiz platform in public beta, with content prevalently around programming (JavaScript and dev quizzes feature heavily in its public docs examples). QuizBase covers general trivia across all domains — over a million questions blended from 11 open sources, EN + PL at parity today, 5-level calibrated difficulty grading (`trivial` to `expert`), multi-layer taxonomy (categories, subcategories, tags, curated topics, and cultural regions), and a Free tier that works in production from day one — 500 requests/day, no credit card.

When to use QuizBase

Your trivia use case is broader than programming — history, science, geography, arts, sports, entertainment, language, culture (we cover 24 categories across a deep taxonomy)
Volume matters — over a million questions versus a small focused corpus
Difficulty grading matters — 5-level calibrated difficulty per question, from `trivial` to `expert`
You need EN + PL today (333k each on `?quality=high`) or other languages on demand
Developer surface matters — OpenAPI 3.1, TypeScript SDK on npm, MCP server with OAuth 2.1 for Claude Desktop / Cursor / ChatGPT, IETF rate-limit headers, RFC 9457 errors, public status page
