Pricing
Start free, pay-as-you-go. New accounts begin with free credits — no card required. When you need more, top up and pay only for what you use: $1 = 7,500 credits, and credits never expire. All API prices below are per minute of audio processed (input duration unless noted).Minimum top-up: 10,000.
Premium variants and modes. Some services charge a multiplier on the base
rate:
- Music Generation — AudioMusic Premium (
dit_variant="xl"): 2× the base rate ($0.08/min). - Stem Separation — premium packages:
karaokeandvocal_genderare 1.5× (0.20/min). Plain modes (2stem/4stem/6stem/16stem) bill at the base $0.10/min.
TTS billing model. API wallet bills TTS by the duration of the generated
audio, not by character count. The per-character rate shown elsewhere in the
docs applies to account-credit billing (subscription plans), not to API-wallet
billing.
Noise Reduction is currently billed from your account credit balance
(subscription plan credits), not from the API wallet. To use noise reduction
programmatically, sign in to your account and obtain a session — the API-key
- wallet path for denoising is not yet enabled.
