How to use the Seedance 2.0 API
Four steps from signup to a finished generation. Full Python, Node.js, and cURL examples are in the API section below.
- 1
Get an API key
Sign up for a WaveSpeedAI account and copy your API key from the dashboard. New accounts come with free starter credits — enough to run the playground a few dozen times before billing kicks in.
- 2
Submit a prediction
POST your input as JSON to https://api.wavespeed.ai/api/v3/bytedance/seedance-2.0/text-to-video. The endpoint returns a prediction id immediately — generations are async so you don't hold an open connection during inference.
- 3
Poll for completion
GET https://api.wavespeed.ai/api/v3/predictions/{request_id}/result. Start around every 2 seconds, then increase toward 5-10 seconds for long-running tasks to reduce unnecessary requests. Stop on completed, failed, cancelled, or timeout.
- 4
Read the output URL
Once status is"completed", read the URL from data.outputs[0]. The URL points to your generated media on the WaveSpeedAI CDN — image, video, audio, or 3D file depending on the Seedance 2.5 variant you called.
What you can build with Seedance 2.5
Common workflows developers and creators use the Seedance 2.5 API for.
Seedance 2.5 API for 30-second single-shot video
Seedance 2.5 is planned for 30-second single-shot native video output, reducing the need to stitch multiple short clips when you need one continuous camera move, performance beat, or product scene.
High-reference brand and character workflows
The coming 2.5 release is expected to greatly increase reference material capacity, with up to 50 attached reference files. That makes it a better fit for brand kits, character packs, multi-shot style boards, and campaign-level continuity.
More controllable text-to-video generation
Seedance 2.5 is positioned around stronger control for video generation: clearer creative direction, better use of attached references, and more predictable prompt-to-motion behavior for production workflows.
Prompt-guided video editing with preserved motion
For editing workflows, Seedance 2.5 is expected to improve prompt-guided changes on existing footage while preserving the source composition, subject identity, and motion intent.
Seedance 2.5 API migration planning
Teams can build against the WaveSpeedAI prediction flow now, then swap the model endpoint when Seedance 2.5 becomes available. Authentication, async polling, result handling, and billing all stay inside the same API platform.
Use Seedance 2.0 API today
Until Seedance 2.5 is live, WaveSpeedAI exposes the current Seedance 2.0 family for text-to-video, image-to-video, video-edit, and video-extend. The endpoints below are the live models you can test now.
Tips for prompting Seedance 2.5
Practical advice for getting better outputs from Seedance 2.5 — drawn from the patterns that work across video models in production pipelines.
Plan for one continuous 30-second shot
Seedance 2.5 is expected to support 30-second single-shot native video output. Write prompts around a continuous action arc: opening frame, camera move, subject action, environmental change, and final frame.
Treat references like a production packet
With up to 50 reference files expected, organize references by role: character, product, environment, wardrobe, motion style, color palette, and brand examples. Cleaner reference intent should translate into more controllable output.
Keep using Seedance 2.0 for live API tests
Until Seedance 2.5 launches, the playground, endpoint cards, pricing, examples, and API samples on this page use the current Seedance 2.0 family. Use those endpoints for production traffic today.
Separate generation and editing prompts
The 2.5 positioning calls out more controllable generation and editing. For generation, describe shot design and motion. For editing, describe what should change and what must stay locked from the source clip.
Avoid overloading all 50 references without labels
More reference capacity helps only when references have clear purpose. In your prompt, name what each reference group should control so style, identity, motion, and scene guidance do not compete.
Seedance 2.0 API pricing
Pricing is per-output. The final charge scales with the parameters you set in each variant's playground (resolution, duration, output count, references).
Call the Seedance 2.0 API
Sign up for an API key at wavespeed.ai/accesskey, then submit a prediction via REST. The playground generates ready-to-paste samples for any combination of inputs.
