Glowbar

Glowbar is a New York-founded skincare studio chain offering expert 30-minute customized facials delivered by licensed estheticians across roughly 25 studios, sold through a monthly membership ($65/month for one facial, $120/month for two) alongside an $85 non-member walk-in price and a direct-to-consumer retail storefront of professional skincare products. Glowbar is not a software vendor and publishes no developer program, but its glowbar.com storefront runs on Shopify and therefore exposes a genuine, callable, unauthenticated agent surface: an agents.md / llms.txt agent instruction document, a Universal Commerce Protocol (UCP) merchant profile at /.well-known/ucp, and a live MCP endpoint at /api/ucp/mcp that answers tools/list anonymously with 13 catalog, cart, checkout and order tools carrying full JSON Schema 2020-12 input schemas. Appointment booking itself runs on a third-party platform (Boulevard) at bookings.glowbar.com and publishes no contract.

Glowbar publishes 1 API on the APIs.io network. Tagged areas include Company, Skincare, Beauty, Retail, and Commerce.

Glowbar’s developer surface includes engineering blog, support, pricing, signup flow, and 11 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/glowbar: open an issue to ask a question, or submit a pull request to add artifacts.
