Liquid Death

Liquid Death is a Los Angeles beverage company founded in 2014 by Mike Cessario, Pat Cook and JonRyan Riggins, selling still and sparkling mountain water, iced tea, flavored sparkling water, the Death Dust electrolyte powder and a Sparkling Energy line, all in recyclable aluminum tallboys and marketed through a deliberately horror-comedy brand voice. It has raised roughly $264M and was valued at $1.4B in its 2024 Series F. Liquid Death publishes no conventional developer portal, yet it is one of the more agent-forward direct-to-consumer storefronts in the catalog: liquiddeath.com serves a first-party agents.md (mirrored at /llms.txt), a dedicated agentic-discovery sitemap, an agent policy block inside robots.txt, a Universal Commerce Protocol merchant profile at /.well-known/ucp, a live UCP shopping MCP endpoint, and both OpenID Connect and RFC 8414 OAuth discovery documents for its customer account. The storefront exposes an anonymous read-only product and collection JSON surface, while every cart, checkout and order capability is confined to the identity-gated, idempotency-keyed MCP transport that requires contemporaneous human approval before payment.

Liquid Death publishes 1 API on the APIs.io network: Storefront Read-Only JSON API. Tagged areas include Company, Beverages, Consumer Packaged Goods, Direct to Consumer, and E-Commerce.

Liquid Death’s developer surface includes documentation, getting-started guide, authentication, FAQ, support, engineering blog, and 27 more developer resources.
