What it does

Linkup is a web search API for AI apps: ask a question and get results with page content, or a short answer with its sources, for example to let an assistant cite current news. Requests are JSON POST calls with a Bearer API key. Free with a free API key: $20 of credit at sign-up with a work e-mail address, topped up to $20 each month for eligible accounts. An official MCP server at https://mcp.linkup.so/mcp lets AI agents search the web and fetch pages.
