Data Licensing Alliance vs Opendatabay

Data Licensing Alliance is a marketplace for licensing STEM datasets for artificial intelligence and machine-learning work. Buyers search available data, while prediction technology suggests additional or alternative datasets. A buyer can license an entire dataset or a subset such as figures, paragraphs, or images, then set intended use, users, and duration in a clickwrap license. Data owners set prices, rights, permissions, and contractual limits. Delivery may use an API key, FTP transfer, or another owner-selected method. The marketplace offers machine-readable formats and standards; DLA’s consulting service lists JSON, FHIR, FSIR, and JATS conversions. Owners receive reporting on licensees, searches, views, licenses, and transactions. DLA states that owners retain raw-data ownership while buyers own derivative datasets or knowledge graphs. Sellers pay $100, capped at $1,000, plus transaction fees.

Opendatabay is a marketplace for buying and selling datasets intended for AI and large language model use. Its listings span text, image, audio, video, code, agentic trajectories, 3D spatial, tabular, time-series, human feedback, and synthetic data. The documentation describes AI-powered search and recommendations, and says datasets are curated and labelled for model training or fine-tuning, with a claimed 20–40% reduction in preprocessing time. Buyers receive licensing terms and provenance information; the company says sellers undergo verification and due diligence. Both free and paid data products are offered, with provider-set prices for paid items. Sellers can list for free, while self-serve sales incur commissions ranging from 30% on sales of $1–$100 to 5% on sales of $250,001 and above. Registered users who complete onboarding can download evaluation samples, but production, commercial use, model training, and redistribution require a separate license or purchase agreement. The service is available on web and through an API. Only registered businesses, legal entities, or institutions may register as providers, and proof of business identity may be required.
