Example

curl -X POST "https://api.aiveed.io/v1/generate/video" \
  -H "X-API-Key: $AIVEED_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "seedance-v1-pro",
  "prompt": "A golden retriever puppy chasing soap bubbles in a sunlit garden, slow motion",
  "resolution": "480p",
  "duration": "5",
  "aspect_ratio": "9:16"
}'

The response is a job — poll GET /v1/jobs/{id} or use webhooks/SSE; when status is completed, result_url is the hosted output.

Good to know

• image_url and first_frame_url are aliases here — either works (first_frame_url wins if both are sent).
• Accepts first_frame_url but not last_frame_url — sending a last frame returns 422.
• Reference media (reference_*_urls) is not supported — 422.
• aspect_ratio applies to text-to-video only — image-to-video output follows the input image.
• Prompt cap: 20,000 characters.
