Sync Labs pricing per second, and a Sume dry_run cost preview

Sync Labs is usage-based: you pay a monthly plan fee plus a rate per second of video, $0.05 per second on Hobbyist and Creator and $0.0475 on Growth. Its sync-3 page separately lists $0.107 to $0.133 per second at 25 fps. Sume's way to know a cost before spending is dry_run=true on a paid MCP tool, which returns an admission and cost preview without submitting the job.

How is Sync Labs priced?

How do I check a cost on Sume before paying?

Write and paid MCP tools require an idempotency_key. Add dry_run=true to get an admission and cost preview only; the docs say not to submit the job from that call. They also suggest generation_admission_preview before expensive bursts, and max_spend_usd, enforced only when you provide it, as a cap.

What if the balance is too low?

A generation submit fails with 402 insufficient_credits before provider work starts. The price itself depends on the model and options: for avatar video, quality accepts standard, plus (default) or max, so preview each tier you plan to use. Per-clip numbers for avatar video are in avatar video pricing per minute.

Does a dry run work like the Hedra and Replicate estimates?

It plays the same role as a price check ahead of a paid call; see Hedra's estimate endpoint vs Sume dry_run for that comparison.
