OK Capsule
OK Capsule is an on-demand, private-label supplement manufacturing and fulfillment platform. Health brands, telehealth providers, clinics and retailers use it to launch personalized daily vitamin packs without minimum order quantities, inventory or upfront deposits. The platform exposes its whole supply chain programmatically: a REST Core API V2 (199 operations across clients, consumers, orders, order lines, fulfillments, assemblies, batches, billings, product lines, pack builders and UPC codes) and a production remote MCP server that publishes the same catalog, pack-building, order and fulfillment surface as OAuth 2.1 scoped tools for Claude, ChatGPT, Gemini and other MCP hosts. Supplements are manufactured in cGMP-certified, FDA-registered facilities and lot-tested by ISO 17025 accredited third-party labs.
OK Capsule publishes 42 APIs on the APIs.io network, including Assemblies API, Authentication API, Batches API, and 39 more. Tagged areas include Supplements, Nutrition, Health, Manufacturing, and Fulfillment.
OK Capsule’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 26 more developer resources.
