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 is listed with 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.

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):

Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
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
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too

4 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 10.4 — up to +22.4 composite points
Access Clarity scores 34.2 — up to +13.2 composite points
Developer Ergonomics scores 35.7 — up to +12.9 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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. This rating is computed from the provider profile at artifacts.apis.io/poppi/apis.yml: open an issue on github.com/api-evangelist/poppi to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Food Safety (GFSI-recognised certification)	undeclared	-	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
