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 every 1-2 seconds. The response includes a status field; keep polling until it flips from "queued" or "processing" to "completed".
- 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 2.0 variant you called.
What you can build with Seedance 2.0
Common workflows developers and creators use the Seedance 2.0 API for.
Cinematic short films
Storyboard a scene with text, pin keyframes from references, and let Seedance 2.0 generate a 5–15s clip with native audio and continuous camera moves — no post-production needed for a draft cut.
Music videos with lip-sync
Upload a track and a character reference; Seedance 2.0 generates a music video with rhythm-driven cuts, lip-sync, and consistent character identity across shots.
Product demos & ads
Drop a product image and a prompt; Seedance 2.0 produces a polished 360° showcase or a use-in-context demo with realistic physics and camera tracking.
Pre-visualization for film & games
Generate animatics from script beats. Reference up to 9 images + 3 videos + 3 audio clips for character consistency across shots.
Editorial B-roll
Quickly fill cutaways with stock-style footage matched to a scene description — cheaper and faster than licensing stock libraries.
Tips for prompting Seedance 2.0
Practical advice for getting better outputs from Seedance 2.0 — drawn from the patterns that work across video models in production pipelines.
Be specific about camera moves
Mention concrete cinematography vocabulary — orbit, dolly-in, push-in, pan-left, crane shot, handheld follow. Generic prompts produce static or arbitrary camera choices; named camera moves map directly to motion intent in the model's training data and dramatically improve shot quality.
Anchor character identity with reference images
If your prompt depends on a specific person, character, or product, upload a reference image alongside the prompt. Without a reference, identity drifts across frames and across shots — the same character ends up looking like a slightly different person each generation.
Describe lighting and time of day
Lighting cues like 'golden hour, soft warm directional light' or 'overcast diffused light, slate-grey sky' improve quality and consistency far more than vague quality modifiers. Lighting is one of the strongest priors the model conditions on.
Use negative prompts to suppress common failure modes
Useful negatives for video: 'frame flicker, motion blur, watermark, text artifacts, distorted hands, low resolution, jpeg compression'. Negative prompts cost nothing and noticeably reduce the rate of generations you'd otherwise re-roll.
Pick the shortest duration that captures your beat
Most prompts work best at 5-8 seconds. Longer clips amplify temporal inconsistencies (subject morphing, environment drift). If you need a 20-second sequence, generate three 6-8 second clips and edit them together — quality stays higher than one long generation.
Match aspect ratio to platform up front
9:16 for TikTok / Reels / Shorts, 16:9 for landscape feeds and YouTube, 1:1 for post grids. Models train slightly differently per aspect ratio — cropping a 16:9 to 9:16 after the fact loses both fidelity and the composition the model intended.
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).

When to pick Seedance 2.0 over similar models on WaveSpeedAI.
Seedance 2.0 vs Veo 3.1
Veo 3.1 leads on photorealism and human faces; Seedance 2.0 wins on motion physics + native audio + multi-reference workflow. Seedance is also typically faster (sub-2-minute generation) and significantly cheaper per second.
Seedance 2.0 vs Kling 3.0
Kling 3.0 produces longer takes (up to 30 s) with strong character consistency. Seedance 2.0 has better instruction adherence, multimodal inputs (audio reference!), and a Fast tier that undercuts Kling on price.
Seedance 2.0 vs Wan 2.7
Wan 2.7 ships 1080p natively and has a stronger image-edit story. Seedance 2.0 is the better choice when you need cinematic motion, native audio in the same generation, or precise camera language.
