"research": { Deep Research $0.015 Searches Wikipedia (opensearch + full-text), Hacker News, and DuckDuckGo when reachable, fetches the top public pages, and returns a cited answer from those pages. Uses extractive sentences, or an OpenRouter model when OPENROUTER_API_KEY is set. Returns no sources and a reason if nothing could be fetched. Creative or generative requests (poems, stories, essays) get a 400 before payment.
