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.

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

    and developers.celanese.com do not resolve, api.celanese.com presents no matching certificate, the real github.com/Celanese
    organization publishes zero public repositories, seven package registries return zero first-party libraries, and the only
    digital product (the Chemille material-selection assistant at materials.celanese.com) is a browser app for engineers that
    ships no API, no llms.txt and no .well-known document.'
