Liquid Death Catalog API

  title: Liquid Death Storefront Read-Only JSON Catalog API
  version: '2026-08-01'
  summary: The anonymous, read-only product and collection JSON surface Liquid Death publishes for AI agents.
  description: 'Liquid Death runs its direct-to-consumer store at https://liquiddeath.com on Shopify. The store

    publishes an agent-facing instruction document at `/agents.md` (mirrored at `/llms.txt`) that

    explicitly documents a **read-only browsing** surface for "agents that only need to read store data

    without transacting". No authentication is required for any operation in this document.


    This OpenAPI was GENERATED by the API Evangelist enrichment pipeline from the endpoints Liquid Death

    documents in `/agents.md`, and every operation below was probed live on 2026-08-01 and confirmed to

    return the recorded status and content type. Schemas were derived from observed response bodies.

    Nothing here is invented: no operation appears that was not both documented by the provider and

    verified against the live host.


    Transactional operations (cart, checkout, order) are **not** in this document. Liquid Death exposes

    those over the Universal Commerce Protocol (UCP) MCP endpoint — see `mcp/liquid-death-mcp.yml` and

    `mcp/liquid-death-ucp-shopping-mcp.openrpc.json`. The provider''s robots.txt explicitly directs agents

    to UCP/MCP for catalog, cart and checkout, and disallows scripted checkout completion.
