# Tags API

> Use the Tags API at /api/taxonomy/v1 to manage Domino Taxonomy namespaces, tags, properties, and their associated operations.

The Tags API manages the Domino Taxonomy and Properties features: namespaces,
[tags](/6.3/platform-capabilities/core-concepts/knowledge-management/tags), and
[properties](/6.3/platform-capabilities/core-concepts/knowledge-management/properties).
It is served at `/api/taxonomy/v1`.

Its endpoints are documented in the
[Domino Platform API reference](/6.3/reference/api/domino-open-api), under the
**Tags** and **Properties** groups. Domino generates every API reference from
the OpenAPI specification each service publishes, and this service's operations
are part of the platform's public API specification, so they render there
rather than on a separate page.
