Poppi

Poppi is an American prebiotic soda brand founded in Austin, Texas by Stephen and Allison Ellsworth, originally as Mother Beverage, rebranded to poppi in 2020 after a Shark Tank investment and acquired by PepsiCo in May 2025. Poppi sells direct to consumers from drinkpoppi.com, a Shopify storefront, and that storefront is where its machine-readable surface lives: poppi publishes agent instructions at /agents.md and /llms.txt, a Universal Commerce Protocol (UCP) merchant profile at /.well-known/ucp, and an anonymous remote MCP endpoint at /api/ucp/mcp exposing 13 catalog, cart, checkout and order tools with full JSON Schema input contracts. Poppi is not a software vendor and ships no developer program, SDKs or OpenAPI — its API surface is the Shopify-native agentic-commerce stack served on and scoped to its own domain.

Poppi publishes 2 APIs on the APIs.io network. Tagged areas include Company, Consumer Packaged Goods, Beverages, Food and Beverage, and E-Commerce.

Poppi’s developer surface includes documentation, authentication, engineering blog, support, and 20 more developer resources.
