LRCLIB

Open synced + plain lyrics database with a totally free, no-key API and timestamped LRC output.

LRCLIB is a free, open lyrics database focused on synchronized (time-stamped) lyrics in LRC format, plus plain text. The API needs no key and the maintainer states it has no rate limiting. The canonical /api/get endpoint matches on artist, track, album, and duration and only returns a hit when the duration is within ~2 seconds, which keeps results tight; there is also a fuzzy /api/search (max 20 results, no pagination). It is the most practical genuinely-free source for karaoke-style synced lyrics in 2026.
