Verdicts

Google Lyria

$0.08 a full song on lyria-3.5 and $0.04 a 30-second clip, flat. No free tier for Lyria, so billing is needed before the first call.

Mubert API

Hosted MCP server with 21 tools and OAuth 2.1 with PKCE, in the official registry under com.mubert. Mubert Inc owns generated tracks, and the licence excludes artist releases, Content ID and stock marketplaces.

Before you call either

Google Lyria

  1. Draft on lyria-3-clip-preview at $0.04 before paying for a full song
  2. Put the target length and structure in the prompt, e.g. "[0:00 - 0:10] Intro" or "a 2-minute song"
  3. Decode output_audio.data from base64 straight to a file. Don't let it into the context
  4. Don't name artists or paste song lyrics. The safety filter blocks the request
  5. Back off exponentially on 429 RESOURCE_EXHAUSTED. Limits are per project and tier

Mubert API

  1. Search the library before generating. A match costs no generation
  2. Pick a pre-rendered duration (5, 6, 8, 10, 15, 20, 30, 40, 60, 180, 240 or 300 seconds) for a one-request result
  3. Download tracks straight away. URLs expire after 900 seconds by default
  4. Treat stream URLs as secrets. They carry the customer access token
