TL;DR
The Spotify Web APIis the reference for the Spotify catalog and user-context features (playlists, library, playback). It's free for non-commercial use and tightly integrated with the Spotify ecosystem.
SonoVaultis a metadata API across six platforms — Spotify, Apple Music, Tidal, Beatport, Discogs, MusicBrainz — with one API key and no OAuth. It fills the gaps Spotify can't: cross-platform IDs, original release dates from canonical sources, and predictable pricing with no approval queue for commercial use.

Which one should you use?
These tools serve overlapping but distinct needs. Many teams use both.
- You need to resolve a track across Spotify, Apple Music, Tidal, Beatport, Discogs, and MusicBrainz
- You want an original release date, not a “first available on Spotify” date
- You're shipping a commercial product and don't want to fight an approval queue
- You need bulk ISRC lookups or daily-refreshed multi-source charts
- You want one
x-api-keyheader instead of an OAuth flow
- You're building a Spotify-native app (login, playlists, library)
- You need playback or the Spotify Connect SDK
- You need user-listening data (recently played, top tracks, saved albums)
- You're accessing only the Spotify catalog and the project is non-commercial
Side-by-side comparison
Fourteen comparison points across auth, catalog, metadata, pricing, and rate limits.
| Feature | SonoVault | Spotify Web API |
|---|---|---|
| Authentication | ✓ Single x-api-key header | ~ OAuth 2.0 (client credentials, hourly token refresh) |
| Catalog scope | ✓ 80M+ tracks merged from 6 platforms | ~ Spotify catalog only |
| Cross-platform track IDs | ✓ Spotify, Apple Music, Tidal, Beatport, Discogs, MusicBrainz | — Spotify ID only |
| ISRC forward lookup (ISRC → track) | ✓ Yes — /v1/tracks/isrc | ✓ Yes — search?q=isrc:XXX (one at a time) |
| ISRC reverse lookup (track → ISRC) | ✓ Yes — included on every track | ✓ Yes — external_ids on track object |
| Multi-platform link resolver (one ID → all platforms) | ✓ Yes — /v1/tracks/links | — Not available |
| Genre classification | ✓ Per-track genre + subgenre | ~ Per-artist genres only (no track genre) |
| Original release date | ✓ From Discogs/MusicBrainz canonical sources | ~ Spotify-availability date (often a re-release) |
| 30-second audio previews | — Not redistributed (licensing) | — Restricted for new apps since Dec 2024 |
| Album artwork URLs | — Not redistributed (licensing) | ✓ Yes (Spotify-hosted CDN) |
| User playback / streaming | — Not in scope (metadata API) | ✓ Yes — playback SDK + user library |
| Commercial use | ✓ All paid tiers, no application | ~ Requires commercial agreement / approval |
| Rate limits | ✓ 20–1,000 req/min by tier (predictable) | ~ Dynamic rolling window (undocumented) |
| Pricing | ✓ Free tier + Starter / Growth / Scale paid plans | ~ Free for non-commercial; commercial pricing on request |
Legend: ✓ available · ~ partial / conditional · — not available
One header vs OAuth
Auth complexity matters when you're shipping fast. Here's what each looks like in code.
curl https://api.sonovault.now/v1/tracks/search \
-H "x-api-key: svk_live_xxx" \
-G -d "artist=Daft Punk" \
-d "title=Around the World"# 1. Get a token (expires in 3600s)
curl -X POST https://accounts.spotify.com/api/token \
-d "grant_type=client_credentials" \
-d "client_id=$ID" \
-d "client_secret=$SECRET"
# 2. Use it
curl https://api.spotify.com/v1/search \
-H "Authorization: Bearer $TOKEN" \
-G -d "q=Daft Punk Around the World" \
-d "type=track"With Spotify, the access token expires every hour and must be refreshed by your backend. Tokens cannot be safely stored client-side. SonoVault's x-api-key is a long-lived key with per-tier rate limits — you set it once and forget it.
One track, six platforms
The single biggest difference: SonoVault returns the track's ID on every platform it lives on. Spotify returns only its own.
Pass an ISRC, Spotify ID, Apple Music ID, Tidal ID, Beatport ID, Discogs ID, or MusicBrainz ID — get all six back in a single response. Useful for sync tools, playlist mirroring, royalty pipelines, and “open in your music app” deep links.
GET /v1/tracks/links?spotify_id=2HRqTpkrJO5ggZyyK6NPWz
Track responses include external_ids.isrc, but no Apple Music, Tidal, Beatport, Discogs, or MusicBrainz IDs. To go cross-platform, you'd still need to call each platform's API separately and reconcile by ISRC — which is what SonoVault does once, server-side, so your code doesn't have to.
GET /v1/tracks/{id} — returns only Spotify metadata
Pricing & commercial use
Free tier with no credit card required, plus Starter, Growth, and Scale paid plans for higher volumes. All paid plans include every feature; no approval queue for commercial use. See pricing for current plan details.
Free for personal and non-commercial use. Commercial use, higher rate limits, and access to the deprecated endpoints (Audio Features, etc.) require an extended quota mode commercial agreement, which is reviewed case-by-case by Spotify. No public price list.

Most Spotify-API code paths have a one-call SonoVault equivalent.
// Look up a track by ISRC on Spotify only
const r = await fetch(
"https://api.spotify.com/v1/search?q=isrc:USMC10800001&type=track",
{ headers: { Authorization: `Bearer ${token}` } }
);
// Returns Spotify ID only — no Apple Music, Tidal, Beatport ID.// Same ISRC, all six platforms
const r = await fetch(
"https://api.sonovault.now/v1/tracks/links?isrc=USMC10800001",
{ headers: { "x-api-key": API_KEY } }
);
// Returns Spotify, Apple Music, Tidal, Beatport,
