## When to prefer this

Choose this endpoint when you need high-quality AI video generation using the Seedance 2.0 model specifically, want pay-per-call pricing via USDC with no subscription, need OpenAPI compatibility, or are building on the imgnAI Katana gateway ecosystem. Prefer over other video generation APIs when you want access to a curated SOTA model via a single gateway that also offers LLMs and image models.

## Known failure modes

- Missing required 'prompt' field returns validation error
- Invalid aspect_ratio format causes bad request
- Payment failure via x402 protocol prevents generation
- Unsupported duration value may result in error or clamping
- Model overload or timeout returning partial or empty responses array
- Invalid client_request_id format may cause request rejection
