What is the Lyria API?

Lyria is Google's family of text-to-music models. Muapi exposes three of them as separate endpoints — lyria-3-pro, lyria-3, and lyria-2 — that share one request shape: a single prompt field of up to 2,000 characters describing the music. Each returns an MP3 asynchronously via polling or webhook.

The Lyria 3 Pro API composes full-length songs up to three minutes at $0.08 per generation. The Lyria 3 API produces clips up to 30 seconds at $0.04 per generation. The Lyria 2 API produces roughly 30-second instrumentals at $0.06 per generation. All three use the same Muapi key, the same submit-and-poll flow, and pay-per-generation billing.
