Generate video with the Seedance 1.5 Pro API

Seedance 1.5 Pro runs on Crazyrouter behind a unified asynchronous video endpoint: submit a task, poll for the result, pay per generated second.

What is Seedance 1.5 Pro?

Seedance 1.5 Pro is a Seedance video model from ByteDance for text-to-video and image-to-video generation. Crazyrouter wraps it in the same task API used for every video model in the catalogue, so switching between vendors is a one-line change.

Unified task API

One submit/poll flow for every video model on Crazyrouter.

Per-second billing

Charged for generated seconds at the resolution-specific rate; failed tasks are not billed.

Text and image inputs

Start from a prompt or a reference frame where the upstream model supports it.

Shared balance

Same key and balance as your chat and image workloads.

Seedance 1.5 Pro API quickstart

Submit a job to https://api.crazyrouter.com/v1/video/generations with model doubao-seedance-1-5-pro, then poll the returned task id until the status is completed.

Seedance 1.5 Pro FAQ

Is generation synchronous?

No. The submit call returns a task id; poll the matching query endpoint (second example above) until it completes.

How is it billed?

Per generated second at the rate for the requested resolution and mode; the range on this page covers the available options.

Which durations and resolutions are available?

Those exposed by the upstream model; pass duration, resolution and aspect ratio as documented.

Can I start from an image?

Yes for image-to-video capable models: include the image URL in the request.

How long do results stay available?

Download the result promptly after completion; upstream links expire.
