X Developer Platform: Build with Real-Time Global Data
What if you could tap into the world’s public conversation as it happens? The X Developer Platform makes that possible. It provides modern APIs to access a massive stream of real-time data—posts, users, trends, and more—giving developers the tools to build, analyze, and innovate.
Forget rigid subscriptions. The platform now operates on a straightforward pay-per-usage model. You only pay for what you consume, with the flexibility to scale instantly. Need another incentive? Purchasing X API credits can earn you free credits for xAI’s API, turning your development budget further.
Core Products for Every Developer
The platform is built around three main pillars, each serving a distinct need.
X API: The Foundation of Public Conversation
This is your direct pipeline to X’s global data. Search historical posts, stream real-time conversations, or analyze trends and user information. It provides programmatic access to posts, users, Spaces, Direct Messages, lists, and media. Whether you’re building a research tool, a brand monitoring dashboard, or a creative visualisation, this API is your starting point.
X Ads API: Automate Your Advertising
Manage complex advertising campaigns directly from your own systems. The X Ads API allows for the programmatic creation, management, and optimisation of ad campaigns. Adjust targeting, update creatives, and pull analytics reports without ever logging into the main ads interface. It’s built for efficiency and scale.
X for Websites: Engage Your Audience
Bring the energy of X directly to your website or blog. With simple embed codes, you can display specific posts, curated timelines, or follow buttons. It’s a powerful way to increase engagement and keep fresh, dynamic content on your site with minimal effort.
Flexible Pricing That Grows With You
Why pay for capacity you don’t use? The platform’s credit-based, pay-per-usage system eliminates monthly subscriptions and minimum spends. You purchase credits and consume them based solely on your API calls. Scale your usage up or down daily with no long-term commitment.
For organisations with high-volume, mission-critical needs, Enterprise tiers offer dedicated support, complete data streams, and options for custom integrations. This ensures reliability and direct partnership as your projects grow.
Here’s a compelling twist: spending on X API credits doesn’t just buy you data access. Depending on your total spend, you can earn back up to 20% of that amount in free credits for the xAI API. It’s a direct benefit for developers working across both ecosystem.
Getting Started and Finding Support
You can go from sign-up to first API call in minutes. The Quickstart guide walks you through getting your API keys and making a simple request. When you’re ready to build, comprehensive documentation includes an API Reference for all endpoints and official Python and TypeScript SDKs to speed up development.
Beyond the basics, the platform is supported by a rich resource hub. Step-by-step Tutorials cover common use cases and integrations. You’ll find a collection of official Tools & Libraries alongside community contributions for various programming languages.
Stuck on a problem? The Developer Forum is where the community and the X team collaborate to solve issues. To stay ahead of changes, subscribe to the monthly Newsletter and regularly check the Changelog for updates on new features and API modifications. For operational status, the API Status page provides real-time availability information, while the Developer Console is your dashboard for managing apps, monitoring usage, and purchasing credits.
The X Developer Platform removes the barriers between your ideas and the world’s most dynamic social data stream. With flexible pricing, powerful tools, and a clear path to start building, what will you create?
