Deep Web Research

Agentic web research via You.com: give it a research question and it autonomously searches, reads, and synthesizes many sources into a cited markdown report with a source list. Four effort tiers (research_effort): lite for quick overviews (seconds), standard for solid multi-source answers (default, ~30s), deep for thorough investigations (~2 min), exhaustive for maximum-depth reports (up to 5 min). Deeper tiers cost progressively more credits. Supports domain include/exclude/boost filters, freshness windows, and country localization. Prefer search_web_grounded for quick fact lookups; use this when the user wants researched, synthesized, citation-backed depth.
