Endpoints: search ($0.005-0.006 per request, 1-3 s), fetch for URL content extraction ($0.001-0.006, under 2 s, optional JS rendering and raw HTML) and asynchronous research ($0.25-2.50, 1-10 min). Filters include include/exclude domains, date range and max results. The hosted MCP server at `https://mcp.linkup.so/mcp` (Streamable HTTP) exposes search, fetch and deep-research tools; the open-source server repo is MIT. Pay as you go; the pricing page says the first 4,000 queries are free. SOC 2 Type II on all plans; zero data retention on Enterprise.
