X ships official Python and TypeScript XDKs, a local API Playground and docs.x.com

What this means for you

X made new building blocks for people who create apps that work with X. There is an official toolkit for two popular coding languages, and a practice copy of X that runs on a developer's own computer, so they can test without posting for real or paying. For people who just post, nothing changes.

The details

• XDKs (November 3, 2025): official first-party Python and TypeScript XDKs for API v2. They handle authentication (Bearer Token, OAuth 2.0 PKCE, OAuth 1.0a), automatic pagination and real-time streaming with reconnect handling, and cover all v2 endpoints. Install with pip install xdk or npm install @xdevplatform/xdk. The Python XDK is generated from X's OpenAPI specification and supports Python 3.8 and above.
• X API Playground (December 23, 2025): a self-hosted local server that emulates API v2 endpoints, with mock data, state persistence, OpenAPI validation, rate-limit simulation and a web UI. Install with go install github.com/xdevplatform/playground/cmd/playground@latest.
• Docs site (January 13, 2025): X launched docs.x.com as its developer documentation site. When we checked on November 7, 2026, the old developer.x.com/en/docs/x-api address redirected to the docs.x.com home page, not to the matching page, so old deep links need updating by hand.
• Related: the xurl command-line tool for API testing launched on December 17, 2024 and supports OAuth 2.0.

What to do next

• Business owners: Nothing.
• Marketers and agencies: Nothing.
• Developers: Try the XDK for new X integrations, run tests against the Playground, and replace developer.x.com documentation links with docs.x.com ones.
