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

  detail: 'The only API Aerial Partners markets — the "Gtax Network API" on its Gtax Network page — has no reference, no spec
    and no signup: the page ends by directing every enquiry to the corporate contact form, and ADM and AWA are sold the same
    way, so nothing about the contract is readable without a sales conversation.'
