Search the SonoVault catalog (93M+ tracks) by artist and title. Both are required; there is no free-text search. Returns ISRC, genre, duration, BPM, musical key, artist credits, and release info (album, label, release date) per track. Tempo and key: bpm (full tempo, e.g. 123) and musical key in three notations: key_alphanumeric (e.g. '10B'), key_musical (e.g. 'D', 'F#m') and key_open (Open Key, e.g. '3d'), plus keys[] with one entry per source. All null (keys empty) when the track has not been analysed.

Fetch one track by its SonoVault track ID, with full metadata (ISRC, genre, duration, BPM, musical key, artist credits, releases). Tempo and key: bpm (full tempo, e.g. 123) and musical key in three notations: key_alphanumeric (e.g. '10B'), key_musical (e.g. 'D', 'F#m') and key_open (Open Key, e.g. '3d'), plus keys[] with one entry per source. All null (keys empty) when the track has not been analysed.

Exact lookup of a recording by its ISRC (International Standard Recording Code, e.g. GBDUW0000053). Returns the track's full metadata, including BPM and musical key. Tempo and key: bpm (full tempo, e.g. 123) and musical key in three notations: key_alphanumeric (e.g. '10B'), key_musical (e.g. 'D', 'F#m') and key_open (Open Key, e.g. '3d'), plus keys[] with one entry per source. All null (keys empty) when the track has not been analysed.

Find the ISWC work code(s) behind a recording, by ISRC or SonoVault track ID. Useful for royalty and publishing workflows. One recording can carry several ISWCs (medleys, samples).

List every recording of a musical work by its ISWC (e.g. T0710204399 or T-071.020.439-9). Returns recordings sorted by popularity, each with a representative ISRC.

Resolve a track to its ID and deep link on every supported platform: Spotify, Apple Music, Tidal, Beatport, Discogs, MusicBrainz, YouTube. Identify the track by exactly one of: SonoVault id, ISRC, or any platform's ID.

Resolve up to 100 inputs in one call to canonical tracks plus cross-platform links. input_type picks the key: 'track_name' (items are {artist, title} objects), 'isrc', 'sonovault_id', or a platform id type ('spotify_id', 'applemusic_id', 'tidal_id', 'beatport_id', 'discogs_id', 'musicbrainz_id'). A discogs_id item is a Discogs track key (release ID plus track position, e.g. '2844-A'), not a bare release ID. Each matched track carries the same fields as get_track, including BPM and musical key. Costs one API credit per line.

Search artists by name. Returns id, name, country, formation year, release count, and the wikidata_id and musicbrainz_id identifiers for joining against external datasets.

An artist's releases, newest first. Use the cursor from a previous call for the next page. Optional from/until (YYYY-MM-DD, inclusive) limit it to a release-date range.

Search record labels by name. Returns id, name, and release count.

A label's releases, newest first, with artist per release. Cursor-paginated. Optional from/until (YYYY-MM-DD, inclusive) limit it to a release-date range; pass the same day for both to see what the label released that day.

Search releases by title, optionally narrowed by artist name.

Fetch one release by SonoVault release ID, including its full tracklist with ISRCs, BPM and musical key per track (same bpm/key_* fields as get_track, null when not analysed). Tracks come back in playing order, each with disc_number and track_number; a track whose position is unknown sorts last with both null. A SonoVault release groups every edition of an album onto one record, so the response also carries an editions array naming the real editions behind it, each with its provider, format, release date, barcode, country, track count, label and catalog number (pressings of one album often carry different labels); pass one of their ids as edition to render that edition's numbering instead of the default consensus. musicbrainz_release_ids and musicbrainz_release_group_ids are arrays for the same reason.

The canonical SonoVault genre hierarchy: 25 main genres plus subgenres, with IDs.

Discover tracks by filter: label ID, artist ID, genre name or genre ID (from list_genres), or release year. At least one filter is required. Needs a paid SonoVault tier; free-tier keys get a 403.
