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 is listed with 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.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)

10 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 0.0 — up to +25.0 composite points
Access Clarity scores 28.9 — up to +14.2 composite points
Contract Governance scores 18.2 — up to +9.8 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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 the provider profile at artifacts.apis.io/nominal/apis.yml: open an issue on github.com/api-evangelist/nominal to ask a question or point us at an artifact you publish.
