ISWC API
ISWC lookup
& reverse search
Developer reference: find the ISWC work code(s) for a recording, or list every recording of a composition from a single ISWC.
Not a developer? Use the free ISWC lookup tool — no code required.
Recording → ISWC
Enter an ISRC or a SonoVault track ID to find the composition code(s) behind that recording. A single recording can carry several ISWCs.
