nTop

nTop (formerly nTopology) is computational design and engineering software for advanced and additive manufacturing. Its field-driven, implicit modeling engine lets engineers build reusable, logic-driven design workflows and systematically explore hundreds of design variants with manufacturing constraints, performance requirements, and simulation built in — spanning lattices, conformal structures, design-for-additive-manufacturing, and topology-informed optimization across aerospace, automotive, medical, and industrial applications. Beyond the desktop application, nTop exposes a developer surface: the nTop Core SDK (a native Windows DLL with C++, .NET, and Python bindings for querying implicit bodies), nTop Automate for headless workflow automation, extensive Mintlify-hosted documentation, and a public documentation MCP server for agent-based retrieval.

nTop is profiled on the APIs.io network. Tagged areas include Company, Manufacturing, Computational Design, Additive Manufacturing, and Engineering Software.

nTop’s developer surface includes documentation, API reference, getting-started guide, changelog, support, engineering blog, signup flow, and 10 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/ntop: open an issue to ask a question, or submit a pull request to add artifacts.
