Strengths

✓

Four ways in

Text, image references, first/last frame (`options.imageRole: "first_frame"`), or a reference video in `options.referenceVideoUrl` — the workflow is picked from what you send.

✓

Reference video

Restyle or continue an existing clip: pass a public MP4 or MOV URL and describe the change (3–10 seconds).

✓

Multi-shot prompts

`multi_shots`, `multi_prompt`, `shot_type`, `elements`, and `mode` go in `options.params`.

✓

Optional audio

Off by default ($0.144/sec); `generateAudio: true` adds a synced track for $0.192/sec.

Kling O3 API — reference-driven AI video

Kling O3 is built around references. Besides plain text-to-video, it accepts image references for characters and objects, a first and last frame to interpolate between, or a reference video to restyle or extend, producing 3 to 15 second clips in 16:9, 9:16, or 1:1.

On YepAPI the input shape picks the workflow: send `imageData` for an image reference, add `options.imageRole: "first_frame"` (and `options.params.last_frame_url`) for keyframes, or `options.referenceVideoUrl` for a video. Billed from $0.144 per second, $0.192 with audio.
