Seedance video API, billed by the frames you get

Official channels behind a single API key. If a channel fails, the task continues on another route under the same ID and is charged once. Failed tasks are free.

New route, same task

When it is unclear whether an upstream accepted a job — a timeout, for example — the platform checks first and never blindly generates twice.

  1. Accepted and reserved — You get a task ID; the maximum possible cost is reserved.
  2. Route A generates — The healthiest official route by priority takes the job.
  3. Route A fails — If it rejects or fails the job, you do not resubmit anything.
  4. Moves to route B — Same task ID; assets are prepared on B when needed.
  5. Saved, charged once — The result is stored, then billed on actual usage; the rest is released.

Three ways in, one task system and one bill

Use the platform API for new projects. Projects already on the official Ark SDK or OpenAI Videos migrate by swapping the base URL and key. All three share one task queue, failover policy, ledger and call log.

  • Platform API: POST https://api.ail.run/v1/videos/generations
  • Ark-compatible: https://api.ail.run/api/v3
  • OpenAI-compatible: https://api.ail.run/v1/videos

Private asset library

Uploads and URL imports are kept here under a fixed asset ID. On failover, copies are rebuilt from the original on the new route. Virtual portraits and authorized real-person portraits are supported.

Results stored for you

Results are copied to our storage before delivery and kept for 7 days; fetch a fresh download link any time, independent of 24-hour upstream links.

Every charge is traceable

Reservations, settlements, releases and grants are separate ledger entries searchable by task ID and reference number; monthly statements reconcile to the cent.

Controls on every key

Each key has a model allowlist, total and daily spending limits, expiry, request and concurrency limits, an IP allowlist and permissions; secrets are shown once.

Frequently asked questions

What is AILink?

AILink is an API for ByteDance's Seedance video generation models. One API key reaches several upstream channels; if a channel fails, the task continues on another one under the same task ID and is charged only once.

Which models can I use?

Seedance 2.0 (seedance-2.0-standard) generates 4–15 second videos at 480P / 720P / 1080P / 4K: text to video, first frame to video, first and last frame to video, multimodal reference (images, video, audio). It can generate synchronized audio. A 5-second 16:9 clip starts at 0.35 USD (480P). Seedance 2.0 Fast (seedance-2.0-fast) generates 4–15 second videos at 480P / 720P: text to video, first frame to video, first and last frame to video, multimodal reference (images, video, audio). It can generate synchronized audio. A 5-second 16:9 clip starts at 0.28 USD (480P). Seedance 2.0 Mini (seedance-2.0-mini) generates 4–15 second videos at 480P / 720P: text to video, first frame to video, first and last frame to video, multimodal reference (images, video, audio). It can generate synchronized audio. A 5-second 16:9 clip starts at 0.18 USD (480P). Seedance 2.5 (seedance-2.5) generates 4–30 second videos at 480P / 720P / 1080P: text to video, first frame to video, first and last frame to video, multimodal reference (images, video, audio). It can generate synchronized audio. A 5-second 16:9 clip starts at 0.52 USD (480P).

How is a video priced?

By video tokens: width × height × frames ÷ 1024 of the output video, times the price per million tokens for its resolution. With reference videos, their length is billed too, at the with-video rate. For example, a 5-second 16:9 480P clip on Seedance 2.0 costs about 0.35 USD. Failed, cancelled and timed-out tasks are free; the maximum possible cost is reserved at submission and whatever is not used is released.

Am I charged when a generation fails?

No. When an upstream channel fails, the platform moves the task to another channel under the same task ID (up to 4 channels), and when it cannot tell whether an upstream accepted a job it checks first instead of generating twice.

Can I keep using the Volcengine Ark SDK or the OpenAI SDK?

Yes. The Ark-compatible endpoint is https://api.ail.run/api/v3 and the OpenAI Videos-compatible endpoint is https://api.ail.run/v1: change the base URL and API key to migrate. The platform's own API is https://api.ail.run/v1/videos/generations.

How long are generated videos kept?

7 days. Results are copied to our storage before delivery, and you can get a fresh download link at any time within that period, independent of 24-hour upstream links.
