Advanced Ionics

Advanced Ionics is a Milwaukee, Wisconsin based clean-energy hardware company developing the Symbion water-vapor electrolyzer, a green hydrogen production technology that uses process and waste heat together with low-cost renewable or nuclear electricity to cut the energy needed per kilogram of hydrogen to roughly 35 kWh, well below the 50-plus kWh required by conventional commercial electrolyzers. Founded in 2017 and relocated to Milwaukee in 2018, the company targets decarbonization of heavy industry — steel, ammonia, refining and other hydrogen-intensive sectors — and has run pilot and demonstration projects with Shell through its GameChanger program and with the Entrepreneurs Fund of the Repsol Foundation, and signed a collaboration MOU with ACWA Power. Advanced Ionics manufactures electrolyzer hardware; it does not operate a public developer program, and no public API, SDK, or machine-readable specification was found.

Advanced Ionics is profiled on the APIs.io network. Tagged areas include Company, Energy, Hydrogen, Clean Energy, and Electrolyzer.

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
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
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)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes

12 more unmet checks in the Agent Readiness table above.

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