Soylent

Soylent is a nutrition company known for its plant-based, complete-nutrition meal-replacement drinks, powders, and bars, sold direct-to-consumer through its Shopify-powered online store at soylent.com.

This profile captures that agent-commerce and authentication surface.

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