45-8 ENERGY

45-8 ENERGY is a French exploration and production company, founded in 2017 and headquartered in Metz with offices in Lyon, dedicated to helium and natural (native) hydrogen in Europe. It is the first company in France and Western Europe specialised in the exploration and production of these two low-carbon subsurface gases, covering the full value chain from geoscientific exploration through production, distribution and recycling. In 2024 it delivered the first helium produced on Western European soil, and it operates RECYCL'He, Europe's first mobile helium recovery and recycling unit. Its exploration and production portfolio spans France (Fonts-Bouillants, Avant-Monts, Marensin, Beauvoir), Germany (Guhlen, Brimir), the Balkans and the United States (Humboldt, Fayette). In April 2026 Ad Terra took a majority stake in the company. 45-8 ENERGY is a physical-resources operator and publishes no developer program, public API, SDK or machine-readable data surface.

45-8 ENERGY is profiled on the APIs.io network. Tagged areas include Company, Energy, Helium, Natural Hydrogen, and Natural 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.

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/.

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/458energy: open an issue to ask a question, or submit a pull request to add artifacts.

  detail: 45-8 ENERGY drills for helium and natural hydrogen; the entire public site is 62 corporate pages enumerated from
    its own sitemap with no developer, docs or data section, and the only machine-readable surface on the domain is the stock
    WordPress REST API at /wp-json/ whose 23 namespaces are all WordPress core or third-party plugins (Elementor, Yoast, Contact
    Form 7, OceanWP, Polylang), not a 45-8 ENERGY product.
