AG1

AG1 (formerly Athletic Greens) is a direct-to-consumer health and nutrition company founded in December 2010 by Chris Ashenden and headquartered in Carson City, Nevada. It sells a single flagship product - AG1, a daily foundational nutrition powder - on a subscription model through drinkag1.com, and the brand was renamed from Athletic Greens to AG1 in December 2021. Revenue grew from roughly $160M in 2021 to approximately $600M in 2024, with a valuation near $1.2B reported in January 2025, built largely on podcast and creator affiliate marketing. AG1 is a consumer commerce business rather than a developer-facing API provider - it publishes no developer portal, no API reference and no OpenAPI - but its Shopify storefront at shop.drinkag1.com does expose a real, anonymously reachable agentic commerce surface: a Universal Commerce Protocol (UCP 2026-04-08) merchant profile at /.well-known/ucp, a Storefront MCP server at /api/mcp, a UCP/MCP commerce endpoint at /api/ucp/mcp, a Customer Account MCP server at account.drinkag1.com, an introspectable Shopify Storefront GraphQL API, and published agents.md / llms.txt / robots.txt agent instructions. Authentication for customer-scoped surfaces is Shopify customer accounts OAuth 2.0 + OpenID Connect with PKCE.

AG1 publishes 4 APIs on the APIs.io network. Tagged areas include Company, Consumer, Health, Nutrition, and Supplements.

AG1’s developer surface includes FAQ, support, signup flow, documentation, authentication, and 18 more developer resources.
