  title: Cometeer Storefront (read-only agent surface) Products API
  version: '2026-08-01'
  summary: Public, unauthenticated JSON endpoints of the Cometeer online store.
  description: 'Cometeer publishes a read-only browsing surface for agents in its own

    `/llms.txt` under the heading "Read-Only Browsing (No Authentication

    Required)". This document is a faithful OpenAPI rendering of exactly the

    endpoints Cometeer names there, with schemas derived from live observed

    responses on 2026-08-01. It is NOT a Cometeer-authored specification, and

    it is NOT the transactional surface — carts, checkouts and orders are only

    reachable through the UCP MCP endpoint catalogued in

    `mcp/cometeer-mcp.yml`.


    Provenance: generated from https://cometeer.com/llms.txt; every path below

    was probed and returned HTTP 200. No endpoint has been invented.
