Prometheus Fuels

Prometheus Fuels is a Santa Cruz, California energy company founded in 2019 by Rob McGinnis and launched out of Y Combinator, producing carbon-neutral electrofuels from atmospheric CO2. Its "no-desorb" direct air capture system dissolves CO2 into carbonate ions in water, and its Faraday Reactor hydrocarbon electrolyzer converts that carbon into methanol, gasoline, diesel, jet fuel and renewable natural gas at room temperature and atmospheric pressure using off-grid solar power. The company also markets an Ultra Long Duration Energy Storage (ULDES) product aimed at data-center power, and operates the Titan Forge Alpha pilot plant in Santa Cruz. It is backed by BMW i Ventures, Maersk Growth and Y Combinator. Prometheus Fuels publishes no product API, developer portal or SDK — it is a physical fuels manufacturer. The single machine-readable surface it operates is the WordPress REST API (wp/v2) behind its corporate site at prometheusfuels.ai, which serves anonymous read access to pages, posts, the site's `news-articles` custom post type, categories, tags, media, comments, users, search, taxonomies, types and statuses, with write operations gated behind WordPress application passwords. This profile was enriched by the API Evangelist pipeline from that live surface.

Prometheus Fuels publishes 12 APIs on the APIs.io network, including news-articles API, pages API, posts API, and 9 more. Tagged areas include Company, Energy, Climate Tech, Carbon Capture, and Synthetic Fuels.

Prometheus Fuels’ developer surface includes authentication, YouTube channel, and 17 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/. This rating is computed from github.com/api-evangelist/prometheus-fuels: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you?
