Oatside

Oatside is a Southeast Asian oat milk brand founded in Singapore in 2020 by Benedict Lim, operating as one of Asia's only "full-stack" plant-milk companies — it controls sourcing, R&D and manufacturing from its own facility in Java, Indonesia, using Australian oats. Its barista-oriented range (Barista Blend, Espresso Roast, Caffe Latte, Chocolate, Chocolate Malt, Matcha, Caramel Macchiato) is sold through independent cafes and retail across Singapore, Hong Kong, Indonesia, Vietnam, Thailand, Cambodia, the Philippines, Malaysia, Taiwan, India, the Middle East and Australia. Oatside is a consumer packaged goods company and publishes no developer program, but its direct-to-consumer Shopify storefront exposes a live, anonymous, agent-callable commerce surface: a Universal Commerce Protocol (UCP) merchant profile and an MCP endpoint serving 13 catalog, cart and checkout tools, plus a published agents.md and llms.txt.

Oatside is listed with 1 API on the APIs.io network. Tagged areas include Company, Food and Beverage, Consumer Packaged Goods, Oat Milk, and Plant-Based.

Oatside’s developer surface includes documentation, support, engineering blog, pricing, and 8 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
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)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)

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.
