Drill into a specific URL after search surfaces it. Returns the extracted text content plus metadata. Internal routing: PDFs hit Anthropic Files API for OCR + structured extraction; HTML pages are fetched + text-extracted via readability-style stripping.
Use for: verifying a verbatim quote from a Reddit thread, reading a primary source in full (earnings transcript, research paper), drilling into a vendor product page after search surfaced the URL.
NOT for: discovering new URLs — use search/search_community/search_research first. This tool takes a known URL only.
Optional max_chars 100-50000, default 8000. SSRF-protected: private IPs + localhost blocked.
