Sourced research brief: answer + 5 cited facts as JSON
researchSend one focused research question (any topic: tech, markets, companies, protocols, science, policy). You receive a strict-JSON brief: a 2-4 sentence direct answer, exactly 5 key facts each with a public source URL, the source title and a short verbatim quote that supports the fact, an overall confidence level (high/medium/low), and up to 5 open questions. Every URL is fetched and checked before delivery; no fabricated or paywalled-only sources. Optional constraints (e.g. 'sources from 2025+', 'primary sources only', language) are honored. Output always validates against the published outputSchema. Not legal/financial advice. If a question cannot be answered from public sources, the brief says so explicitly with confidence 'low'.
