Encoder `sourceTrackId` is omitted. Each `track` may include `artworkUrl` (HTTPS) from ingest or from station artwork lookup (Spotify, Apple Music, or Last.fm) after the observation is stored; the field is omitted when no art is known. `elapsedSeconds` and `endsAt` are derived from `track.observedAt` and `track.durationSeconds` at response time (both null when duration is unknown or the track is not playing). The public realtime feed carries the same projection and may send a follow-up update when lookup fills art. ## OpenAPI ````yaml /radiotools/openapi.json get /api/v1/stations/{stationSlug}/now-playing openapi: 3.1.0 info: title: RadioTools API version: 1.0.0 description: >- RadioTools APIs for listener websites and apps, published media, and now-playing metadata ingestion. servers: - url: https://radiotools.rivi.software description: radiotools API security: [] tags: - name: Public listener description: >- Tenant-token published delivery (listener:read; push:register for device changes).
