Twitter/X

X (formerly Twitter) operates the X Developer Platform, giving developers programmatic access to the public conversation through the X API v2 — Posts, Users, Direct Messages, Lists, Spaces, Communities, Community Notes, Trends, News, Media, and real-time delivery via filtered/sample/firehose streams and webhooks (X Activity, Account Activity, Filtered Stream Webhooks). The platform runs credit-based Pay-Per-Use pricing with a Developer Console at console.x.com, first-party Python and TypeScript XDKs, the xurl CLI, a local Playground mock server, and an unusually deep agent-native surface: llms.txt, AGENTS.md, skill.md, and hosted MCP servers for both the API and its documentation.

Twitter/X publishes 22 APIs on the APIs.io network, including Account Activity API, Activity API, Articles API, and 19 more. Tagged areas include Company, Social, Social-Media, Posts, and Real-Time.

The Twitter/X catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Twitter/X’s developer surface includes documentation, API reference, getting-started guide, support, pricing, signup flow, changelog, and 34 more developer resources.
