How much does the Seedance API cost and how is it billed

The Seedance API on RelayDance is billed pay-as-you-go per generated video, priced by output resolution. Seedance 2.0 costs about $0.190 per second at 720p and about $0.470 per second at 1080p, while Seedance Fast runs about $0.152 per second. Native 4K is priced at about $4.90 per 5 second clip.

What are the current Seedance per-second rates

Seedance pricing is set per second of generated video and scales with the chosen resolution. At 720p, Seedance 2.0 is about $0.190 per second; at 1080p, it is about $0.470 per second. The lower-cost Seedance Fast option is about $0.152 per second. For native 4K output, billing switches to a per-clip basis at about $4.90 per 5 second clip. These four published values let you estimate total cost before submitting a task. Live per-model rates are maintained at relaydance.com/models, which is the source of record for the figures above. Choose the resolution that matches your delivery target to control the per-second cost.

How is billing handled, and what about failures

Billing is pay-as-you-go per generated video, charged only for successful output. There are no upfront commitments, and you pay per second (or per clip for native 4K) according to the model and resolution you select. Failed requests carry no charge: "failed or errored requests are never billed", According to the official relaydance.com docs. Payments are accepted via USDT and Stripe card. Access does not require a BytePlus enterprise account or KYC. To begin, create an API key at the console (relaydance.com/console) and authenticate with Authorization: Bearer YOUR_API_KEY. Because errored calls are not billed, retries during testing do not add cost when a request fails.

How do I integrate the Seedance API

Integration uses the OpenAI-compatible protocol, so existing OpenAI SDK code works after changing the base URL. According to the official relaydance.com docs: "set base_url to https://relaydance.com/v1 and keep your OpenAI SDK". Follow these steps:

1. Create an API key at relaydance.com/console.
2. Set base_url to https://relaydance.com/v1.
3. Submit a task with POST /v1/video/generations including model, prompt, and seconds.
4. Poll GET /v1/video/generations/{task_id} until status is succeeded or failed, then read the video url.

You can also set metadata.callback_url for webhook delivery. Reference media (up to 9 images, 3 videos, 3 audio tracks) go in metadata.content[]. See relaydance.com/docs.
