New POST /api/v1/request endpoint accepts a search query from external
sources (Discord bots, Home Assistant, curl) and triggers the
search-match-download pipeline asynchronously. Returns a request_id
for status polling via GET /api/v1/request/<id>. Optional notify_url
for callback on completion.
Also adds webhook_received trigger type and search_and_download action
type to the automation engine, so users can build custom flows like
"when webhook received → search & download → notify Discord".
Includes info panel in Settings showing endpoint URL and curl example.
Seasonal discovery had 3 use_spotify checks using is_authenticated()
(always True) instead of deriving from the configured source. Search API
(tracks, albums, artists) also defaulted to Spotify when authenticated.
All now check configured primary source first via get_primary_source().
Users can now choose between iTunes/Apple Music and Deezer as their free
metadata source in Settings. Spotify always takes priority when authenticated;
the fallback handles all lookups when it's not.
Core changes:
- DeezerClient: full metadata interface (search, albums, artists, tracks)
matching iTunesClient's API surface with identical dataclass return types
- SpotifyClient: configurable _fallback property switches between iTunes/Deezer
based on live config reads (no restart needed)
- MetadataService, web_server, watchlist_scanner, api/search, repair_worker,
seasonal_discovery, personalized_playlists: all direct iTunesClient imports
replaced with fallback-aware helpers
Database:
- deezer_artist_id on watchlist_artists and similar_artists tables
- deezer_track_id/album_id/artist_id on discovery_pool and discovery_cache
- Full CRUD for Deezer IDs: add, read, update, backfill, metadata enrichment
- Watchlist duplicate detection by artist name prevents re-adding across sources
- SimilarArtist dataclass and all query/insert methods handle Deezer columns
Bug fixes found during review:
- Similar artist backfill was writing Deezer IDs into iTunes columns
- Discover hero was storing resolved Deezer IDs in wrong column
- Status cache not invalidating on settings save (source name lag)
- Watchlist add allowing duplicates when switching metadata sources
Adds a full public REST API at /api/v1/ with 32 endpoints covering library, search, downloads, wishlist, watchlist, playlists, system status, and settings. Includes API key authentication (Bearer token), per-endpoint rate limiting, and consistent JSON response format. API keys can be generated and managed from the Settings page. No changes to existing functionality — the API delegates to the same backend services the web UI uses.
