Nominal

Nominal is the unified software suite for testing and operating advanced hardware — flight systems, satellites, robotics, energy, and other mission-critical engineering programs. Nominal Core is a collaborative workspace that captures, monitors, and analyzes multimodal test data (telemetry, logs, video, and simulation results) across datasets, runs, assets, channels, workbooks, and checklists, while Nominal Connect runs at the edge to read from and write to instruments in real time from Python. Nominal exposes an open Conjure-based REST API at api.gov.nominal.io/api, with first-party SDKs for Python, Rust (and the nom CLI), Go, and LabVIEW, plus a documentation MCP server for AI clients. Backed by Founders Fund, General Catalyst, Lightspeed Venture Partners, and Lux Capital.

Nominal publishes 1 API on the APIs.io network. Tagged areas include Company, Deep Tech, Test and Measurement, Hardware, and Aerospace.

Nominal’s developer surface includes documentation, API reference, getting-started guide, engineering blog, signup flow, CLI, authentication, and 16 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/nominal: open an issue to ask a question, or submit a pull request to add artifacts.
