Example use cases include: - Accessing embeddings for a dataset. - Automating the process of dataset creation and model retraining as your data changes. - Much more. Our backend is built using the [FastAPI](https://fastapi.tiangolo.com/) framework in python using [Auth0](https://auth0.com/) and [Client API Keys](https://www.truestate.io/dawn/docs) for internal an external authentication, respectively. Our backend is designed to be secure, scalable, easy to use and well documented _(each router with its own linked docs page)_. Clients can only access data from their own organisation, as setup in Auth0 our the Client API Keys. See how **[here](https://www.truestate.io/dawn/docs)**. **PS**: You can view this API documentation in either **[Swagger](swagger/docs)** or **[Redoc](redoc/)**, but only the swagger lets you test calls. contact: name: True State Support url: https://www.truestate.io/dawn/docs email: support@truestate.io license: name: Private url: https://www.apache.org/licenses/LICENSE-2.0.html version: 0.13.95 servers: [] security: [] paths: /task-templates/{template_id}/versions/: get: tags: -
