Nothing to run from here
FreqBlog Music Metadata is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.

Get audio features for ONE track — BPM, musical key (name + Camelot + Open Key), energy, danceability, valence, acousticness, instrumentalness, liveness, speechiness, loudness, mood, mood_vector, genre, time signature, duration and more. This is the drop-in replacement for Spotify's deprecated /audio-features endpoint. Provide AT LEAST ONE identifier — if you know several, send th
| Parameter | Type | Required | Notes |
|---|---|---|---|
| track | no | Track title. Use with artist when known. Supply AT LEAST ONE of track/isrc/mbid/spotify_id. Sending several is fine — they resolve by precedence (track > isrc > mbid > spotify_id) and the rest are i | |
| artist | no | Artist name. Only used with track; required when the title is <=2 characters. | |
| isrc | no | ISRC, e.g. 'USUM71900001'. | |
| mbid | no | MusicBrainz recording ID (UUID). The precise key when there is no ISRC, e.g. pre-1986 recordings. | |
| spotify_id | no | Spotify track ID, 'spotify:track:...' URI, or open.spotify.com URL. Resolved from our Spotify-ID map or, on a miss, by matching the track's title — a title several artists share is ambiguous and misse |
Get audio features for MANY tracks in one call (up to 50 processed) — ideal for analysing a whole playlist at once. Identify each item by name (track/artist), by isrc (matched exactly first — best for CJK / K-pop / niche tracks whose fuzzy name-match misses), or both (ISRC first, name as the fallback). One bad entry never fails the batch. Items beyond the 50-per-call cap com
| Parameter | Type | Required | Notes |
|---|---|---|---|
| tracks | array | yes | List of {track?, artist?, isrc?} objects. Up to 50 are processed per call; any extra (up to 200 accepted) come back skipped. Each item should carry track or isrc. |
Full-text search the catalog by any mix of track / artist / album tokens. Use this to resolve a fuzzy, partial, or misspelled name into concrete tracks BEFORE calling get_audio_features. Returns lightweight stubs (itunes_track_id, track_name, artist_name, album, etc.) ranked by relevance — NOT audio features. Take the best match's track_name + artist_name and pass them to get_
| Parameter | Type | Required | Notes |
|---|---|---|---|
| q | string | yes | Search query — any mix of artist / track / album tokens. |
| limit | integer | no | Max results (default 10). |
Find catalog tracks near a target tempo. Returns tracks whose BPM is within +/-tolerance of bpm, ordered by closeness then popularity — useful for DJ set planning, workout playlists, or tempo-matching. Each returned track carries full audio features. To also constrain by musical key, combine with find_tracks_by_key.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| bpm | number | yes | Target tempo in BPM. |
| tolerance | number | no | Plus/minus BPM window (default 2). |
| limit | integer | no | Max tracks (default 10). |
Find catalog tracks in a given musical key — for harmonic mixing and key-locked playlists. key accepts Camelot ("8A"), Open Key ("1m"), or a key name ("A-Minor", "F#-Major"). Returns tracks ordered by popularity, each with full audio features. To discover which keys mix well with a given key first, use find_compatible_keys.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| key | string | yes | Camelot ('8A'), Open Key ('1m'), or key name ('A-Minor', 'F#-Major'). |
| limit | integer | no | Max tracks (default 10). |
Given a Camelot key (e.g. "8A", "12B"), return the harmonically compatible keys for DJ mixing — the same key, the relative major/minor, and the adjacent +/-1 keys on the Camelot wheel. With extended=true also returns the +7/-7 energy-boost / energy-drop keys. Pure music theory — no catalog lookup and no quota cost. Pair with find_tracks_by_key to then pull actual tracks in each c
| Parameter | Type | Required | Notes |
|---|---|---|---|
| camelot | string | yes | Camelot key, e.g. '8A' or '12B'. |
| extended | boolean | no | Also return the +7/-7 energy-boost / energy-drop keys. |
Score how well one catalog track mixes into another (0-100) — the pairwise DJ transition score no raw key/BPM API gives you. Combines Camelot-wheel key compatibility, octave-aware BPM proximity (half/double-time counts as a match), and energy smoothness. Returns the overall score, per-component scores (harmonic/tempo/energy), a detail block (key_relation, both Camelot ke
| Parameter | Type | Required | Notes |
|---|---|---|---|
| from_track_id | string | yes | The track you're mixing FROM — a catalog itunes_track_id, e.g. 'apple_ad1829eeccb70f9a'. |
| to_track_id | string | yes | The candidate track you're mixing INTO — a catalog itunes_track_id. |
Given a seed track, return the top-N catalog tracks to play NEXT, ranked by transition score. Each suggestion carries the same score, per-component scores and human reason as score_transition (e.g. "11B->11B same key, 118->117 BPM (-0.29), energy +0.12"), plus its genre and genre_relation to the seed. GENRE-AWARE by default (cross_genre=auto): off-genre picks that only coin
| Parameter | Type | Required | Notes |
|---|---|---|---|
| seed_track_id | string | yes | The track currently playing — a catalog itunes_track_id. |
| n | integer | no | How many next-track suggestions to return (default 10). |
| min_score | integer | no | Drop candidates below this overall transition score (default 0). |
| exclude_same_artist | boolean | no | Drop tracks by the seed's artist (default false). |
| bpm_drift | number | no | Max BPM difference pre-filter before scoring (default 12). |
| max_key_distance | integer | no | Max Camelot-wheel hops pre-filter before scoring (default 2). |
| cross_genre | string | no | Genre handling: 'auto' (default) keeps picks in a mixable genre lane so an off-genre track that only shares key/BPM sinks to the bottom; 'strict' = same genre-family only; 'allow' = genre-blind (harmo |
Order a crate of 2-100 catalog tracks into a beat-matched DJ set that follows an energy arc, keeping each consecutive transition harmonically and tempo-smooth. arc is one of peak_time (default — builds to a peak then eases), warmup, cooldown, or flat. Returns the arc, count, an overall flow_score (0-100), the tracks in play order, the per-step transitions ({from_index,
| Parameter | Type | Required | Notes |
|---|---|---|---|
| track_ids | array | yes | The crate to order — 2 to 100 catalog itunes_track_ids. |

| start_track_id | no | Optional fixed opener — must be one of track_ids. |
Recommended tracks for one or more seed tracks — the drop-in for Spotify's removed GET /v1/recommendations. Blends up to 5 catalog seed tracks into a single point in audio-feature space and returns the nearest catalogue tracks, RE-RANKED by genre affinity (so a feature-close cross-genre track doesn't outrank same-genre picks). Returns seeds (each {id, found}), count, and `trac

|---|---|---|---|
| seed_tracks | no | 1-5 catalog itunes_track_ids to base recommendations on, e.g. ['apple_ad1829eeccb70f9a'] (blended into a feature-space centroid). Omit and use track(+artist) to seed by name instead. | |
| track | no | Seed by track NAME instead of an id — resolved to the best catalog match (echoed back as seed_query). Pair with artist to disambiguate. Ignored when seed_tracks is given. | |
| artist | no | Artist name narrowing the track seed (case-insensitive). | |
| limit | integer | no | Number of recommendations to return (default 20). |
| exclude_seed_artists | boolean | no | Drop tracks by any of the seed artists (default false). |
| cross_genre | string | no | Genre handling (mirrors suggest_next_track): 'auto' (default) re-ranks by genre affinity so a feature-close cross-genre track can't outrank same-genre picks; 'strict' = same genre-family only (off-gen |

| max | no | HARD upper bounds, e.g. {'tempo': 130}. Same attributes as min. Combine the two for a range. | |
| target | no | PREFERRED values, e.g. {'energy': 0.8}. Tracks nearer the value rank higher; unlike min/max nothing is removed. Same attributes as min. |
Artists related to a seed artist — the drop-in for Spotify's removed GET /v1/artists/{id}/related-artists. No artist graph exists, so we derive one: build the seed artist's track-vector centroid, take its nearest catalogue tracks, aggregate by artist (each scored on its top-3 track similarities so a prolific artist can't dominate) plus a same-genre lift and a cross-genre penalty.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| artist | string | yes | Seed artist name (as it appears in the catalog; case-insensitive). |
| limit | integer | no | Number of related artists to return (default 20). |
Get a compact, HONESTLY-LABELLED tag list for a track — energy / danceability / valence / acousticness / instrumentalness, plus a mood tag and a broad genre tag. It is a tag-shaped projection of the same open-data analysis get_audio_features returns (no audio upload, no extra compute), so it costs the same 1 quota unit, charged only on a served result.

Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.

This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.27.2.
