Music & Audio is a source-level category with 3 free APIs, mostly spanning AI & ML and Media & Entertainment.
This topic page exists to catch the specific language developers actually search for when browsing public API catalogs. Instead of a broad umbrella section, it focuses on the source category label "Music & Audio" and collects the APIs that repeatedly show up under that exact theme.
That makes it especially useful for long-tail discovery. In practice, the strongest patterns in this set are LLM, Memory & Storage, and Search, which often reveals how vendors inside the same topic are really used in products and agent workflows.
If you are comparing options, start with ElevenLabs, Openverse, and The Audio DB and then branch outward into the broader section or capability pages. This gives you both the long-tail entry point and the wider surrounding market context.
