FiftyOne SDK (Python)

The open-source FiftyOne Python SDK is the primary interface for building and curating visual AI datasets - creating Datasets and Samples, slicing data with Views and aggregations, computing embeddings and similarity, running evaluations, and launching the interactive FiftyOne App. Distributed via pip (Apache-2.0); it is a Python library, not a remote REST API.

info:
  title: Voxel51 FiftyOne API
  description: >-
    FiftyOne by Voxel51 is delivered primarily as an open-source Python SDK
    (Apache-2.0), not as a broad public REST API. The SDK creates and curates
    Datasets, Samples, and Views, computes embeddings and evaluations, and
    launches the interactive FiftyOne App locally.


    FiftyOne Enterprise (formerly Teams) adds the fiftyone.management Python
    module and an authenticated API connection: SDK clients set
    FIFTYONE_API_URI and FIFTYONE_API_KEY so calls run against the central
    FiftyOne Enterprise API instead of a direct MongoDB connection. That API is
    an internal GraphQL/orchestration surface consumed by the FiftyOne SDK and
    App; Voxel51 does not publish a general-purpose public REST contract, so no
    REST paths are modeled here. This document intentionally exposes an empty
    `paths` object to accurately represent the SDK-first interface rather than
    fabricating endpoints.


    Authentication for the Enterprise API connection is via per-user API keys
    (generated in the App under Settings > API keys, or via
    fiftyone.management.generate_api_key()); all actions are authorized as the
    user the key belongs to, enforcing roles and dataset permissions.
