Physna

Physna is a geometric search and 3D deep-learning platform that lets you search, compare, analyze, and organize 3D models and physical parts by their actual geometry rather than by filename or metadata. Its public REST API (v2, OpenAPI 3.0) exposes model ingestion and reprocessing, geometric search (part-to-part, part-in-part, part, scan, visual, and geo-related matches), image-based search, collections and folders, model/collection metadata and metadata keys, assembly-tree traversal, match reports, user management, and client-credential provisioning. The API is JSON over HTTPS, is authenticated with OAuth 2.0 through Physna's Okta authorization server, and is used to detect duplicate designs, discover alternative components, and organize design inventory across manufacturing, engineering, and AI training use cases.

Physna publishes 8 APIs on the APIs.io network, including ClientCredentials API, Collections API, Deprecated API, and 5 more. Tagged areas include Company, Ai, 3D, Geometric Search, and Manufacturing.

Physna’s developer surface includes authentication, documentation, API reference, getting-started guide, engineering blog, support, signup flow, and 16 more developer resources.
