GET /web-answer
unprobed
Quick web answer with citations (Exa upstream): ask one factual or current question and get a concise synthesized answer plus source URLs and publication dates. Optimized for fast lookups and agent loops; use /llm-research for a deeper multi-section research report, reasoning, image analysis, or webpage summarization. Keyless, pay-per-call, cached by query.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
