Technical details
Endpoint
POSThttps://kat.imgnai.com/v1/videos/generationsWhen to prefer
Choose this endpoint when you need to generate videos from text prompts using frontier or proprietary AI video models (Seedance 2.0, Happy Horse, etc.) and want pay-per-call pricing via USDC with no subscription. Prefer this over general-purpose video APIs when you need access to cutting-edge or niche proprietary models through a single unified gateway.
Side effects
- Invalid or unsupported model name returns an error
- Duration value out of acceptable range causes rejection
- Missing required fields (model, prompt, or duration_seconds) returns a 400-level error
- Payment failure (x402) if USDC balance is insufficient
- Prompt content policy violation causing generation refusal
- Timeout if video generation takes too long
