https://api.segmind.com/v1/kling-o3-image2videoParameters
image_urlrequiredstring (uri)The starting image to animate. This will be the first frame.
promptrequiredstringDescribe the motion and animation to create from the image.
durationoptionalstringLength of the output video in seconds.
"5""3""4""5""6""7""8""9""10""11""12"+3 moreend_image_urloptionalstring (uri)The ending image. Animation will transition from start to end.
generate_audiooptionalbooleanEnable to generate synchronized audio with the video.
falsemodeoptionalstringSelect quality mode. Standard for faster generation, Pro for higher quality.
"pro""std""pro"multi_promptoptionalobject[]Array of prompts with durations for multi-segment video.
promptoptionalstringPrompt for this segment.
durationoptionalstringDuration for this segment in seconds.
shot_typeoptionalstringCamera shot type for the video.
"customize"Response Type
Returns: Video
Asynchronous requests (v2)
Use Async for video, long-running (>~60s), or high-concurrency workloads; Sync is simplest for fast image & LLM calls. Async submits a request and you poll it to completion.
- 1
POST /v2/kling-o3-image2videoSubmit — returns request_id, status_url, response_url
- 2
GET /v2/requests/{id}/statusPoll — until COMPLETED or FAILED
- 3
GET /v2/requests/{id}Result — final response body
Status states
- A FAILED request is served as HTTP 422 — the body still carries the error detail.
- An unknown or expired request_id returns HTTP 404.
- Results are retained for 1 hour, then expire.
- Content / RAI blocks surface as FAILED, not a separate state.
- Track completion by polling the status endpoint.
Common Error Codes
