It's keyless and free, now on its 6th major version — the previously indexed v3 endpoint is deprecated in favor of v6.vbb.transport.rest.
Open-data API behind Grenoble metro area's "M" mobility site (SMMAG), covering the transit network's stops, lines, real-time schedules (via an embedded OpenTripPlanner instance), and shared-mobility points like Métrovélo bike lockers and Citélib car-share stations.
