  title: TIER / Dott GBFS Discovery Zones API
  version: '2.3'
  description: 'Public GBFS (General Bikeshare Feed Specification) 2.3 endpoints for TIER / Dott shared micromobility systems. After the 2024 TIER + Dott merger, all GBFS feeds are served under the unified ridedott.com infrastructure at https://gbfs.api.ridedott.com/public/v2. Each city or zone is a separate "system" identified by a slug (e.g. `berlin`, `paris`, `london`, `madrid`, `dubai`). The API exposes a discovery document plus a standard set of GBFS feeds: system information, vehicle types, station information, station status, free-floating vehicle status, geofencing zones, and system pricing plans. All endpoints are unauthenticated and return JSON.'
