Seedance API Guide: Developer Access & Integration

Building AI video generation into your own application? Seedance 2.0's API gives developers programmatic access to the full generation engine—text-to-video, image-to-video, multimodal references, and native audio. This guide covers access methods, pricing tiers, available providers, and what to expect as the API ecosystem matures.

API Access Status (February 2026)

Seedance 2.0's direct API is scheduled to launch in late February 2026 through BytePlus (ByteDance's enterprise platform). In the meantime, several third-party providers already offer API access to Seedance models.

API Pricing Tiers

Tier Price per Minute Resolution Features
Basic~$0.10720pText-to-video, image-to-video only
Pro~$0.301080pAdds native audio generation
Cinema~$0.802KFull features: audio + multi-shot + multimodal refs

Prices vary by provider. Third-party platforms may add margins or offer volume discounts. Some providers offer free starter credits for testing.

What the API Supports

Input Types

  • Text prompts — Full prompt support with all Seedance features
  • Image uploads — Reference images for character, background, product
  • Video uploads — Motion and camera reference (up to 3 videos)
  • Audio uploads — Soundtrack and audio sync reference (up to 3 audio files)

Output

  • Video file — MP4 at specified resolution (720p / 1080p / 2K)
  • Audio track — Embedded in video (native generation)
  • Duration — 4-15 seconds configurable
  • Aspect ratios — 16:9, 4:3, 1:1, 3:4, 9:16

Generation Modes

  • Text-to-video — Prompt only, no references
  • Image-to-video — First frame / last frame mode
  • Multimodal reference — @ tag system with up to 12 files

Integration Considerations

Processing Times

  • Standard clip: ~60 seconds
  • Complex multimodal (15s): Up to 10 minutes
  • Queue during peaks: Additional wait time possible

API calls are asynchronous—submit a generation request, receive a job ID, poll for completion or use webhook callbacks.

Rate Limits

Vary by provider and plan. Third-party providers like WaveSpeedAI support up to 10 concurrent renders. Enterprise plans through BytePlus offer custom concurrency limits.

Content Policies

All API access is subject to Seedance's content safety policies. Biometric filters and content moderation apply to API generations just as they do to the web interface. See the safety section in our Seedance 2.0 guide for details.

Enterprise Features

For production-grade deployments, BytePlus enterprise plans include:

  • Custom rate limits and concurrency
  • SLA guarantees — 99.99% uptime
  • SOC 2 Type II certification
  • HIPAA alignment (for applicable industries)
  • Volume discounts
  • Dedicated support
  • Private deployment options

Getting Started

  1. Choose a provider — WaveSpeedAI or Replicate for immediate access; BytePlus for enterprise
  2. Get API key — Sign up with your chosen provider
  3. Test with Basic tier — Start at 720p text-to-video to understand the workflow
  4. Upgrade as needed — Move to Pro (audio) or Cinema (full features) for production
  5. Read the Prompt Guide — Prompt quality is the biggest factor in API output quality

Frequently Asked Questions

Q: Is the Seedance API available now?

A: The official BytePlus API is launching late February 2026. Third-party providers (WaveSpeedAI, Replicate, Fal.ai) already offer API access to Seedance models.

Q: How much does API access cost?

A: From ~$0.10/minute (Basic, 720p) to ~$0.80/minute (Cinema, 2K full features). Third-party pricing varies. Some providers offer free starter credits.

Q: Can I generate audio through the API?

A: Yes, on Pro and Cinema tiers. Basic tier generates video only. Audio is embedded in the output video file.

Q: What about rate limits?

A: Varies by provider. Typical third-party limits are 5-10 concurrent renders. Enterprise plans offer custom concurrency through BytePlus.

Q: Is there a free tier for testing?

A: Some providers offer free starter credits. For interactive testing before committing to API integration, use Dreamina's free daily tokens.

Q: How does Seedance's API compare to Runway's?

A: Runway's API is more mature (available longer, better documented). Seedance's API offers more capabilities (multimodal input, native audio, longer duration). As Seedance's API ecosystem matures, the documentation gap will close.
