Cirkul, Inc. is a Tampa, Florida direct-to-consumer beverage company founded in 2016 by Garrett Waggoner and Andy Gay. Cirkul sells a reusable bottle system paired with patented flavor cartridges — called Sips — that sit in the bottle lid behind a dial, letting a drinker adjust flavor intensity without pre-mixing. The cartridge lines include LifeSip, FitSip and GoSip, covering more than 100 zero-sugar, zero-calorie flavors spanning fruit blends, iced teas, iced coffees and caffeinated and electrolyte formulations. Cirkul does not publish a general-purpose developer API or an OpenAPI definition; its machine-readable surface is an agent-commerce one, served from its own drinkcirkul.com Shopify storefront: an anonymous Model Context Protocol server at /api/mcp, a Universal Commerce Protocol (UCP) merchant profile at /.well-known/ucp, a UCP shopping MCP endpoint at /api/ucp/mcp, published agent instructions at /agents.md and /llms.txt, and OAuth 2.0 / OpenID Connect discovery for the Shopify Customer Account API.
