# About the Enterprise API — firehose, streams, and webhooks

> Overview of the X Enterprise API, including full firehose access, volume and likes streams, account activity webhooks, custom rate limits, and support.

The Enterprise API provides the highest tier of access to X data. It includes everything available in the standard X API plus exclusive high-volume endpoints, semantic embedding operators for Filtered Stream, custom rate limits, and dedicated account management for organizations that need X data at scale.
