About X

X (formerly Twitter) is a real-time social platform where hundreds of millions of people post, follow the news, and join the conversation — with Grok AI built in. For creators it's a distribution and audience-building engine; for developers, the X API and the new hosted X MCP server make X's real-time data available to AI agents and MCP-compatible tools like Grok and Cursor with no setup, turning X into a live information source for agentic workflows.

Pricing model: Freemium
