  title: Lots Sounds API
  description: 'Search, preview, and download 12,000+ CC0 sound effects and music tracks.


    - **Auth:** send your API key in the `x-api-key` header. Keys need a Pro or Enterprise plan.

    - **Search:** `q` is a case-insensitive keyword search. Each word must match a sound name, description or tag. Combine it with `tags`, `category`, and duration filters.

    - **Rate limits:** Pro 2,500 requests/day, Enterprise 50,000 requests/day. Limits reset at midnight UTC.

    - **Sound licence:** every sound is CC0 1.0 Universal. Commercial use is allowed and attribution is not required.

    - **MCP:** the same catalog is available to AI agents at `https://api.lotsofsounds.com/mcp`.'
