Register LightlyOne Workers and schedule compute-worker runs that execute a selection / active-learning configuration over a dataset, producing curated subsets via embeddings, metadata, and model predictions, plus run artifacts and logs.

title: LightlyOne Platform 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.
