The Musixmatch Lyric Fingerprint API uses its comprehensive database of millions of lyrics and advanced search technology to provide a powerful text-matching service. This enables platforms to identify potential lyrical content in any text and detect potential copyrighted musical material at scale. In today’s generative AI landscape, platforms face the critical challenge of identifying copyrighted material in user-generated text. Lyric Fingerprint acts as a key component, allowing platforms to proactively flag potential copyright concerns and significantly strengthen their compliance strategies. Through a simple POST request to the track.lyrics.fingerprint.post endpoint, developers can submit any text containing at least 10 words and receive a ranked list of matching tracks from the Musixmatch catalog. The response size is customizable via the size parameter, returning 5 results by default with a maximum of 20, allowing platforms to balance between detection accuracy and processing efficiency.
