ClassPass scores C on the API Report Card. ClassPass documents an Inventory API at developers.classpass.com for approved scheduling-software vendors to sync schedules and accept reservation callbacks. Individual studios cannot get keys; they toggle the connector inside their scheduling platform. No consumer booking API exists.
ClassPass has an official API, but teams routinely hit its limits: gated access, partial coverage, or paid tiers. Most end up supplementing it with exports or an unofficial API layer like Supergood.
ClassPass is a global subscription marketplace that lets consumers book fitness classes, gym visits, spa/salon appointments, and wellness experiences across tens of thousands of studios using a single credit-based membership.
POS / Hospitality (Fitness & Wellness Class/Appointment Marketplace). Consumers use the ClassPass app to discover studios near them, browse class/appointment schedules, reserve a spot using monthly credits, check in at the venue, rate the class, and manage their subscription.
ClassPass operates in 31 countries with 30,000+ partner studios commonly cited and 80,000+ listed businesses per recent marketing.
For partner businesses: per-class/per-appointment inventory and availability released to ClassPass, reservation and cancellation history, no-show records, ClassPass-attributed client profiles (with the studio rarely owning the underlying email/phone), per-booking payout rates and statements, dynamic-pricing/yield decisions, and acquisition attribution (94% of ClassPass users are reported as new to the venue they visit).
Founded in 2010 as Classtivity by Payal Kadakia and Sanjiv Sanghavi in New York; rebranded to ClassPass in 2014 after the Passport product validated the multi-studio model.
API access is gated to approved scheduling-software partners; individual studios cannot get keys and must rely on whichever scheduling platform they use to expose the integration. Studios on incompatible scheduling software are forced into 'manual' setup, typing schedules and managing bookings by hand in the Partner Hub. Full sourced list under Sources below.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
