X

X (formerly Twitter) operates the X Developer Platform, the programmable interface to the public conversation on X. The X API v2 is a 190-operation REST surface covering Posts, Users, Direct Messages, the encrypted Chat API, Lists, Spaces, Media, Communities, Community Notes, Broadcasts, News, Trends, Articles and Bots, plus a substantial real-time layer — filtered stream, firehose and sample volume streams, compliance streams, Account Activity webhooks and the X Activity API. X publishes a machine-readable OpenAPI at api.x.com/2/openapi.json, an llms.txt family, an AGENTS.md, an agentskills.io skill, an A2A agent card and two hosted MCP servers. Access is sold pay-per-usage in prepaid credits rather than by subscription tier, with an Enterprise agreement for volume above the published cap.

X publishes 23 APIs on the APIs.io network, including Account Activity API, Account API, Activity API, and 20 more. Tagged areas include Social, Social-Media, Posts, User, and Direct Messages.

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

X’s developer surface includes authentication, CLI, sandbox, changelog, documentation, API reference, getting-started guide, and 39 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/x: open an issue to ask a question, or submit a pull request to add artifacts.
