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 publishes 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 7 more developer resources.
