RelayDance API authentication, keys and payment

RelayDance authenticates every request with an API key passed as an HTTP header: Authorization: Bearer YOUR_API_KEY. Create keys in the console at relaydance.com/console. The interface is OpenAI compatible, so you point your existing SDK at the base URL https://relaydance.com/v1. Payment is pay-as-you-go through USDT or Stripe card, and failed requests are not billed.

How do I authenticate RelayDance requests?

Authentication uses a bearer token in the request header: Authorization: Bearer YOUR_API_KEY. You generate and manage keys in the console at relaydance.com/console. Because the service is OpenAI compatible, you keep your current client library and change only the endpoint. According to the official relaydance.com/docs："set base_url to https://relaydance.com/v1 and keep your OpenAI SDK". This applies to video tasks via POST /v1/video/generations and to image tasks via POST /v1/images/generations, with the same key used across both routes. See the protocol details at relaydance.com/docs.

How do I get and use an API key?

Obtain a key in the console, then attach it to each call as a bearer token.

1. Sign in to the console at relaydance.com/console and create a key.
2. Set base_url to https://relaydance.com/v1 in your OpenAI SDK.
3. Add the header Authorization: Bearer YOUR_API_KEY to every request.
4. Submit a video task with POST /v1/video/generations, then poll GET /v1/video/generations/{task_id} until status is succeeded or failed.
5. For images, call POST /v1/images/generations with the same key.

You can attach reference media in metadata.content[] (up to 9 reference images, 3 reference videos, and 3 audio tracks per request, with clips up to 15 seconds), cited in the prompt as @image1 to @imageN.

What payment methods does RelayDance support?

RelayDance accepts USDT and Stripe card payments on a pay-as-you-go basis per generated video. There is no BytePlus enterprise account or KYC required for OpenAI compatible access to Seedance. Per-model rates are published at relaydance.com/models. Sample current figures: Seedance 2.0 720p is about $0.190 per second, Seedance 2.0 1080p is about $0.470 per second, Seedance Fast is about $0.152 per second, and Seedance native 4K is about $4.90 per 5 second clip. For gpt-image-2, image output is free and billing applies only to input; image-to-image starts at about ¥0.035, and 4K and 1K outputs are priced the same.

Am I charged for failed requests?

No, requests that fail or return errors are not billed. According to the official relaydance.com docs："failed or errored requests are never billed". Billing is pay-as-you-go and tied to successfully generated output, so a request that ends with status failed during polling does not incur a charge. This applies to both the video route (POST /v1/video/generations) and the image route (POST /v1/images/generations). For confirmation of current rates and the no-charge-on-failure policy, consult relaydance.com/models, where live per-model figures are listed alongside the billing terms.
