Sonilo is a pay-as-you-go AI music API: add funds to a dollar balance, then every generation is billed by the second at its product's rate. No monthly subscription required, no seats, and API credits / balance required before real generation.
By the second of processed audio, at the per-product rate shown above. The estimator multiplies your minutes by that rate so you can gauge spend before you top up. For endpoints that accept variants_num, cost scales linearly with the variant count — variants_num=3 costs three times a single-variant request, and the per-product billing floor applies to each variant.
Music generations are capped at 6 minutes. Sound effects from a video accept videos up to 8 minutes, and sound effects from a text prompt are capped at 3 minutes. Longer projects are produced as multiple requests.
Yes. High-volume accounts get a custom rate applied to every generation. Contact our sales team and we'll set it up.
Your dashboard billing page shows your current balance and full transaction history, and lets you enable auto-recharge so you never run out mid-project.
Yes, every generation includes commercial-use output rights. Use generated music and sound effects in client videos, paid ads, YouTube, apps, games, and other commercial projects without additional Sonilo licensing fees.
