  summary: Read-only JSON endpoints over the Brooklinen Shopify storefront.
  description: >-
    Unauthenticated, read-only JSON endpoints over the Brooklinen storefront at https://www.brooklinen.com.
    Brooklinen documents this surface itself, in the "Read-Only Browsing (No Authentication Required)"
    section of https://www.brooklinen.com/agents.md (mirrored at /llms.txt), for agents that need to read
    store data without transacting.


    NOT A PROVIDER-PUBLISHED SPEC. Brooklinen publishes no OpenAPI document. This description was generated
    by the API Evangelist enrichment pipeline from (a) the endpoint list Brooklinen publishes in /agents.md
    and (b) live probes of each endpoint on 2026-08-02. Every path below returned HTTP 200 when probed and
    every schema property below was observed in a real response body — nothing here is invented. Per-operation
    `x-evidence` records the probe. For transactional operations (cart, checkout, order) see the UCP/MCP
    surface at https://www.brooklinen.com/api/ucp/mcp, described in mcp/brooklinen-mcp.yml.
