One API for the music metadata you actually need
Building anything music-related means querying half a dozen APIs, normalizing their data, and reconciling track IDs that never quite line up. Each streaming platform exposes only its own catalog and its own ID format. Discogs has the original release date. MusicBrainz has the canonical IDs. Each comes with its own rate limits, auth flow, and edge cases.
SonoVault aggregates all of it into a single REST API with one API key, one auth header, and one consistent response shape. Whether you're building a DJ app, a recommendation engine, a sync platform, or a research tool, you skip months of plumbing and start with the data already merged and normalized.
What's in the database
Six sources, merged on ISRC and high-confidence artist/title matching, served from a Postgres + Elasticsearch stack tuned for sub-50ms search.
Each source is accessed under its own terms — public data dumps for MusicBrainz and Discogs, official developer APIs for the streaming platforms. See data sources & attribution for how each one is licensed and credited.
Fields available per track
Engineered for scale
Daily ingestion
Cron jobs refresh the catalog every day. New releases and metadata updates are reflected within 24 hours.
Cross-platform matching
ISRC is the primary key when available. When it isn't, normalized artist + title matching with confidence scoring links the same recording across platforms, even when titles differ slightly.
Honest reconciliation
Field-level conflicts between sources are resolved with a confidence-weighted preference per field, so the most reliable available value wins.
Fast search at scale
Postgres for canonical storage, Elasticsearch for fuzzy search, aggressive caching and indexing for sub-50ms p95 search latency on an 80M-row catalog.
Built for music developers
From solo indie projects to commercial music tools, here are the things people are shipping with the API.
Catalog & rights tools
Resolve any platform ID or ISRC to a canonical track with metadata from all six sources. Useful for sync agencies, royalty platforms, and catalog management.
Music recommendation engines
Build genre- and release-aware recommendations on top of a normalized catalog. Cross-platform IDs let users open suggestions on the platform they actually use.
Music discovery apps
Surface new releases and browse by label, genre, or year. ISRC codes mean you only pay royalties on the right master, even when titles overlap.
Indie research & analytics
Bulk lookups by ID list, ISRC search, and date-bounded release feeds make SonoVault useful for music journalists, researchers, and label A&R teams.
How we think about the product
- Builders first. No sales calls, no MSAs, no minimum commitments. Sign up, get a key, ship.
- Honest pricing. Predictable monthly tiers based on request volume. Every feature available on every paid plan.
- Generous free tier. 1,000 requests per month, no card required. Enough to prototype and validate before you commit.
- Stable contracts. Public endpoints are versioned; breaking changes go to a new version. Your code keeps working.
- Data quality over data volume. An 80M-row catalog is only useful if the metadata is correct — we invest heavily in merging, deduplication, and source-weighted reconciliation.
