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 is listed with 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 13 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
