Seedance 2.0 Save Fast API
Seedance 2.0 Save Fast API combines the Fast route with Save restrictions for products, environments and fictional subjects without real human faces.
Seedance 2.0 Save Fast combines ByteDance's accelerated family variant with APINEED's no-real-face routing restriction. It is intended for rapid iteration on eligible product, environment, object, and fictional-character scenes.
Playground
Generate with Seedance 2.0 Save Fast, review the output, and use the same request shape in your application.

Discount
Compare the published baseline with APINEED pricing for Seedance 2.0 Save Fast API. Final generation cost follows completed server usage. [3]
Availability
APINEED monitors Seedance 2.0 Save Fast API availability. Applications should preserve request and task IDs and handle upstream failures explicitly.
Rapid eligible-subject drafts
Use it to iterate on products, environments, animation, abstract visuals, and fictional subjects before selecting a final prompt. [2][3]
No real-face workflows
The Save restriction applies even though the underlying Fast route can otherwise handle broader Seedance inputs. [3]
Seedance family direction
Prompts can still describe motion, camera language, lighting, story progression, and synchronized sound associated with the Seedance 2.0 family. [1][2]
Shared asynchronous lifecycle
Creation and polling use the same APINEED video endpoints, with seconds and metadata assembled from explicit controls. [3]
Fast iteration without real-person inputs
Validate eligibility first. Remove real-person identity requirements before iterating on motion or style.
Compare accepted outputs. Track usable clips and retries, not only the time of the first response.
Escalate deliberately. Use Fast or standard Seedance when a real face is needed; use standard Save when final quality deserves a separate pass.
Quick Start
Call Seedance 2.0 Save Fast with the verified APINEED endpoint and model-specific request shape.
Create an API key
Store your APINEED key server-side as API_NEED_API_KEY.
export API_NEED_API_KEY=sk-apineed-v1-...Send the request
Use seedance-2.0-fast:save with POST /v1/media/generations.
curl https://apineed.com/v1/media/generations \
-H "Authorization: Bearer $API_NEED_API_KEY" \
-H "Content-Type: application/json" \
-d '{

}
}'Poll the task
Save id, then poll GET /v1/media/generations/{id} every few seconds until the task is succeeded or failed.

Seedance 2.0 Save Fast API questions
Practical answers for choosing, integrating, pricing, and operating the Seedance 2.0 Save Fast API on APINEED.
What does Seedance 2.0 Save Fast combine?
It combines ByteDance's accelerated Seedance 2.0 variant with APINEED's Save restriction against real human faces. [2][3]
Which projects fit Save Fast?
It fits rapid prompt iteration for products, environments, objects, abstract visuals, animation, and fictional characters. [3]
What should I use for a real person?
Choose Seedance 2.0 Fast for accelerated real-person work or standard Seedance 2.0 when the full-quality route is preferred. [3]
Does Save Fast have a latency SLA?
No. Fast indicates the accelerated model variant, but APINEED does not guarantee a specific task duration. [2][3]
How do I call Save Fast?
Submit seedance-2.0-fast:save to POST /v1/videos with seconds and the supported metadata fields, then poll the returned task ID. [3]
How is Save Fast priced?
APINEED applies the production Save Fast billing matrix for its supported 720p mode, with separate rates depending on whether the request includes a video reference. [3]
