Labelbox

Labelbox is an enterprise-grade data labeling and AI training data platform that enables teams to build, manage, and evaluate machine learning models. The platform provides a REST API and a GraphQL API (endpoint: https://api.labelbox.com/graphql) for programmatic access to datasets, annotation projects, labels, ontologies, and model evaluation workflows. Labelbox strongly recommends using its official Python SDK rather than querying the GraphQL API directly, as GraphQL endpoints may change without notice. The platform also supports JavaScript/TypeScript through a Node.js SDK and offers notebook-based examples via its GitHub organization.

Labelbox publishes 2 APIs on the APIs.io network. Tagged areas include Data Labeling, AI Training, Machine Learning, Annotation, and Computer Vision.

The Labelbox catalog on APIs.io includes 1 JSON-LD context.

Labelbox’s developer surface includes documentation, engineering blog, pricing, and 15 more developer resources.
