# Songs by ISRC

Source: https://recoupable.dev/docs/api-reference/apple/songs

Look up recordings in the Apple Music catalog by ISRC. Accepts up to 25 comma-separated ISRCs per request and returns one row per **requested** ISRC, so a recording that Apple does not carry comes back explicitly as `found: false` rather than being omitted. Complements `GET /api/spotify/search`, which reaches ISRCs only through a fuzzy `isrc:` search query; Apple matches the identifier exactly and additionally returns release-level rights metadata (`upc`, `record_label`, `copyright`) that Spotify does not expose.
