# Prometheus Fuels

> Prometheus Fuels is a Santa Cruz, California electrofuels company (founded 2019, Rob McGinnis, Y
> Combinator) that turns atmospheric CO2 into carbon-neutral methanol, gasoline, diesel, jet fuel and
> renewable natural gas using a "no-desorb" direct air capture system and its Faraday Reactor
> hydrocarbon electrolyzer, run on off-grid solar. It also markets an Ultra Long Duration Energy
> Storage (ULDES) product for data-center power. It is a physical manufacturer: as of 2026-08-05 it
> publishes NO product API, no developer portal, no SDK and no /llms.txt. The only machine-readable
> surface on its hosts is the WordPress REST API (wp/v2) that serves its own corporate website.

## APIs

Prometheus Fuels operates one machine-readable API surface: the WordPress REST API serving its
corporate website. This is site infrastructure, not a product API. Read operations respond
anonymously; write operations require WordPress application passwords.

- [WordPress REST API discovery](https://prometheusfuels.ai/wp-json/): Root discovery document; 29
  namespaces advertised.
- [wp/v2 route index](https://prometheusfuels.ai/wp-json/wp/v2): 134 routes, self-describing with
  per-route arguments.
- [WordPress REST API reference](https://developer.wordpress.org/rest-api/reference/): The upstream
  human reference for these routes.

Collections that returned HTTP 200 anonymously on 2026-08-05: `posts`, `pages`, `news-articles`,
`categories`, `tags`, `media`, `comments`, `users`, `search`, `taxonomies`, `types`, `statuses`.
Collections that returned 401: `settings`, `menus`, `themes`, `plugins`, `wp-abilities/v1/abilities`.

The `news-articles` collection is the site-specific custom post type carrying Prometheus Fuels press
and news coverage — the one endpoint here that returns company-specific content rather than generic
CMS plumbing.

## Specs

- openapi/prometheus-fuels-posts-api-openapi.yml — 13 operations
- openapi/prometheus-fuels-media-api-openapi.yml — 9 operations

## Semantics

- authentication/prometheus-fuels-authentication.yml — HTTP Basic via WordPress application passwords.
- conventions/prometheus-fuels-conventions.yml — pagination, filtering, field selection, caching, CORS.
- errors/prometheus-fuels-problem-types.yml — the flat WordPress error envelope and its codes.
- data-model/prometheus-fuels-data-model.yml — entity graph and relationships.
- lifecycle/prometheus-fuels-lifecycle.yml — versioning by namespace; no deprecation policy, SLA or status page.
- conformance/prometheus-fuels-conformance.yml — standards conformance, honestly scored.
- security/prometheus-fuels-domain-security.yml — TLS 1.3; no HSTS, DNSSEC, CAA, SPF or DMARC observed.
- skills/ — two packaged Agent Skills grounded in real operationIds.

## Not available

- No developer portal, API reference, pricing, status page, changelog or support surface for any API.
- No OpenAPI, AsyncAPI, GraphQL SDL or Postman collection published by the company.
- No MCP server: /wp-json/mcp returns `rest_no_route`; no `mcp` namespace is advertised.
- No A2A agent card: /.well-known/agent-card.json and /.well-known/agent.json both 404.
- No /.well-known/ documents of any kind, including security.txt.
- No first-party SDK or client library on npm, PyPI or any other registry.
- Nothing about fuel production, ULDES systems, plant telemetry or offtake agreements is exposed
  through any API.
