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

  description: Partner-facing trade-in API behind Valyuu's embedded recommerce platform. Version 1 exposes device catalog
    lookups (categories, brands, series, models, and model condition/attribute questions), FAQ content, trade-in order creation
    and cancellation, item offer confirmation (accept, decline-recycle, decline-return), shipping labels, and paperless shipping
    codes, authenticated with an X-Api-Key header. Documented via a Swagger endpoint referenced by Valyuu's public frontend
