Paying for an AI video API with USDT or card: top up options on RelayDance

RelayDance supports two payment methods for its OpenAI-compatible AI video generation API: USDT and Stripe card. Billing is pay-as-you-go per generated video, so you are charged for each successful generation based on live per-model rates published at relaydance.com/models. Failed or errored requests carry no charge. No BytePlus enterprise account or KYC is required to access Seedance through the API.

Which payment methods does RelayDance accept?

RelayDance accepts USDT and Stripe card payments for topping up your account balance. Billing operates on a pay-as-you-go model, meaning you pay per generated video rather than through a fixed subscription. This structure means costs scale directly with usage, and there is no charge for requests that do not complete. According to the official relaydance.com docs, 「Failed or errored requests are never billed」, so retries after an error do not increase your bill. You create and manage API keys, and monitor balance, through the console at relaydance.com/console. Live per-model rates are available at relaydance.com/models so you can estimate cost before submitting a task.

How much do Seedance video generations cost?

Seedance pricing is set per second or per clip depending on the resolution and variant you select. Below are the published rates, all listed at relaydance.com/models:

Because billing is per second for most variants, a longer clip costs proportionally more, while the native 4K tier is priced per 5-second clip. Since failed requests are never billed, only completed videos count toward your balance.

How do I connect and start billing?

You connect using the OpenAI SDK and your existing code, then top up in USDT or card to begin billing. 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 in your SDK configuration.
3. Authenticate with the header Authorization: Bearer YOUR_API_KEY.
4. Top up your balance using USDT or a Stripe card.
5. Submit a video task with POST /v1/video/generations, then poll GET /v1/video/generations/{task_id} until status is succeeded or failed.

See the full protocol at relaydance.com/docs.

How does image billing differ from video billing?

Image billing on the gpt-image-2 model works differently from per-second video billing: image output is free and only input is billed. Image-to-image requests start from about CNY 0.035, and 4K and 1K output cost the same. Because output resolution does not change the price for images, you can request higher resolution output without a resolution-based surcharge. This contrasts with Seedance video, where resolution directly changes the per-second rate (for example, Seedance 2.0 720p at about $0.190 / second versus 1080p at about $0.470 / second). Images are submitted with POST /v1/images/generations. Current image rates are listed alongside video rates at relaydance.com/models.
