  title: LightlyOne Platform Datasets Embeddings API
  description: REST API for the LightlyOne data-curation and active-learning platform for computer vision. The API manages datasets, samples, embeddings, cloud datasources, selection / active-learning runs (the LightlyOne Worker), tags, and asynchronous jobs. Paths and verbs mirror the OpenAPI-generated client shipped inside the open-source `lightly` Python package (lightly.openapi_generated.swagger_client). The open-source self-supervised learning SDK is a separate, pip-installable library and is not part of this HTTP surface.
