Seedance 2.5 API Providers with Global Access and USD Billing

Seedance 2.5 is available through ByteDance’s separate first-party regional platforms, Volcano Engine Ark for China and BytePlus ModelArk internationally, both of which use token-based billing derived from video input and output duration, resolution, and frame rate, with minimum-token floors for video-input requests. The comparison emphasizes that this metering can make cost forecasting less straightforward than per-second pricing, while third-party providers offer alternative commercial models and access paths. Atlas Cloud is presented as offering three Seedance 2.5 variants at a published $0.134 per output second, with USD billing, multiple payment methods, a $25 minimum top-up, no commitment, automatic refunds for failed video tasks, and stated SOC II, HIPAA, and privacy-law compliance; however, upstream providers retain their own data policies. Other services vary substantially in pricing structure, including resolution- and input-dependent per-second charges, token surcharges, per-run pricing, and credit-based systems, making direct comparisons dependent on matching generation settings. Seedance requests generally use asynchronous submission and status polling or webhooks, supporting 4–30 second outputs in 480p or 720p, while published rate limits and independently validated performance benchmarks remain limited.
