Overview
Answer a question and grade how well the answer actually holds up against independent sources, in one call. Composite: one call runs answer-web + web-search + wikipedia-search + retrieval-rerank + citation-verify in parallel, then maps the answer's sentences onto reranked, re-verified evidence passages. Pass a question to get a generated, cited answer, or pass your own answer as context to grade it instead. Returns a support score, a supported/unsupported verdict, and the exact spans that had no
