Search evidence pack: one web search, then the top 5-8 result pages are read and returned as short quoted passages (up to 3 per page, 300 characters each) with the source link, title, rank and the time each page was read. Extractive only: no AI-written text, no summaries. Pages that fail are listed with the reason. Not charged when the search has no results or no page can be read. USDC on Base only.
