This API gives developers programmatic access to Talqui's services layer, exposing the operations needed to read and manage tenants, conversations, plugins, and related resources that power that platform. Authentication is available on behalf of an Operator (the default for this API), a Plugin Connection, or a Plugin — see the [Talqui authentication guide](https://docs.talqui.chat/guides/introduction/authentication/) for how each token is obtained and when to use it.
