Stegra

Stegra (formerly H2 Green Steel) is a Stockholm-headquartered industrial company, founded in 2020 and backed by Vargas Holding, building what it describes as Europe's first large-scale near-zero-emission steel plant in Boden, northern Sweden. The 270-hectare Boden site integrates a giga-scale electrolyzer producing green hydrogen from renewable Nordic electricity, a direct-reduction plant making green iron without coking coal, and a downstream steel mill — a combination Stegra says cuts steelmaking emissions by roughly 95 percent versus the blast-furnace route. Its commercial products are green steel, green iron and green hydrogen, sold to automotive, construction and appliance customers. Stegra is a heavy-industry manufacturer rather than a software vendor: it operates no public developer portal, publishes no API documentation, and serves no machine-readable API contract. Its only public engineering surface is the stegraab GitHub organization, which maintains community Terraform providers and a tflint ruleset used for its own internal infrastructure.

Stegra is profiled on the APIs.io network. Tagged areas include Company, Steel, Manufacturing, Green Hydrogen, and Energy.

Stegra’s developer surface includes engineering blog, support, and 6 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities 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.
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/.
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/stegra: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: Stegra sells physical green steel, green iron and green hydrogen from its Boden plant under negotiated offtake agreements,
    and its Next.js site carries no developer, API or portal route at all — /openapi.json and /llms.txt answer 200 with the
    application's HTML shell because a catch-all route swallows unknown paths, while every /.well-known/ path returns a real
    404.
