Description: The Taxonomy API is now available to every Amplitude customer, regardless of plan. Starter, Plus, Growth, and Enterprise orgs all have full read and write access via the API with no feature flag or plan gate.

With this feature, users can manage events, properties, and taxonomy at scale through the API, (and, eventually, via MCP tooling) to keep their data clean and reliable.

Where: https://amplitude.com/docs/apis/analytics/taxonomy endpoints now accessible for all orgs. See Taxonomy API docs for full reference.
