Tem

Tem (Tem-Energy Limited) is a UK-based energy technology company building AI-native transaction infrastructure for a modern energy market. Its RED platform is a modern utility that removes wholesale market markups to cut business electricity costs by up to 30%, provides transparent line-by-line billing from half-hourly meter data, and gives generators fairer earnings with renewable-energy traceability across 6,000+ sites.

The customer-facing platform runs at app.tem.energy behind an OIDC login; the platform API at api.tem.energy is a private AWS API Gateway with no publicly documented developer surface at the time of profiling.

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