title: Cometeer Storefront (read-only agent surface) Collections 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.
