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 is listed with 1 API on the APIs.io network. Tagged areas include Company, Energy, Climate Tech, Carbon Capture, and Synthetic Fuels.

Prometheus Fuels’ developer surface includes authentication, YouTube channel, and 18 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.

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
MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
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)
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):

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/prometheus-fuels/apis.yml: open an issue on github.com/api-evangelist/prometheus-fuels to ask a question or point us at an artifact you publish.
