Seed Audio API pricing

bytedance/seed-audio

Sound effects from a description. Seed Audio by ByteDance, routed through INFRO on a ByteDance account you connect — alongside every other provider you run. ByteDance bills you for it directly, on that account and at your own rate. INFRO adds routing, failover, request logs, cost attribution and policy around it, and takes no part of what you pay ByteDance.
