Kling 3.0 Omni API Guide: 4 Endpoints in curl and Python
Kling 3.0 Omni has four endpoints on one task API: text, image, reference-to-video and transformation. Pricing starts at $0.10 per second at 720p; 4K is $0.479. Reference-to-video can use up to 7 images and one reference video; elements lock named subjects.

Kling 3.0 Omni Prompts: 7 Real Clips Across All 4 Endpoints
One subject can move across Omni's endpoints: text-to-video, reference-to-video, then transformation. Reference images carry identity; the prompt carries motion and setting. Name subjects in elements and write @name to keep two subjects consistent.

Wan 3.0 Prime API Guide: Text, First/Last Frame and Reference Images
wan3.0-video-prime handles text, first/last frame and reference-to-video in one model. References can be images, audio, a document or a web page. $0.0875 per second at 480P; a 5-second clip is $0.4375.

Wan 3.0 Prime API Pricing: $0.0875 per Second at 480P
Wan 3.0 Prime bills per second: $0.0875 at 480P, $0.18 at 720P, $0.36 at 1080P. Sound costs nothing extra; clips run 2–30 seconds. resolution defaults to 1080P, so leaving it out costs $0.36 per second.

Kling Transformation Video Restyle API: One Look Across Every Short-Form Clip
kling-3.0-omni/transformation restyles an existing clip from a prompt — it repaints the scene, palette, and texture while keeping the original camera motion and timing, which makes it ideal for giving a short-form series one consistent look. This guide applies a single hand-painted watercolor 'look preset' to two completely unrelated source clips (a city-gutter paper boat and a misty harbor) — both embedded as real 720p outputs that cost about $0.43 each. There is no strength or fidelity slider: the whole restyle is prompt-driven, so one well-written preset becomes a reusable filter you can run across an entire clip library with a short async batch script. For the raw create -> poll -> download mechanics see the companion how-to; this piece focuses on the short-form production workflow: style unification and batch restyling.

How to Prompt Grok Imagine for Image Extension and Outpainting
Send the image to grok-imagine/image-to-image and set aspect_ratio to the new frame. The prompt must lock the subject, describe the fill, and forbid new objects. Grok re-renders the whole image, so check subject position and details.

Kling 4.0 API: Release Date, Announced Specs and What to Use Now
There is no public Kling 4.0 API yet; only a limited Flash version is live in Kling's own app. Announced specs include 30-second clips, 10 keyframes, 15 references and 4K. Kling 3.0 is callable on HiAPI today from $0.10 per second.

Kling 3.0 API in Python: Text-to-Video and Image-to-Video Guide
Kling 3.0 runs on HiAPI as kling-3.0/text-to-video and kling-3.0/image-to-video, with 3–15 second clips up to 4K. Pricing is per second: $0.10 at 720p, $0.143 with sound, $0.129 at 1080p, $0.193 with sound, $0.479 at 4K. One Python script handles both endpoints: submit, poll, and download.

Seedance 2.0 Mini API Guide: $0.0272/s Video in curl and Python
seedance-2.0-mini handles text-to-video, image-to-video and reference-guided video in one model id, with native audio. It costs $0.0272 per second at 480p and $0.0586 at 720p; a 5-second 480p clip is $0.136. resolution is required; requests without it fail.

Fastest Image Generation API? We Timed 9 Models End to End
FLUX.2 Klein 4B was fastest at a 16.6-second median, and the cheapest at $0.00143 per image. FLUX Schnell, Grok Imagine and Z-Image finished in 26–28 seconds. GPT Image models took over a minute, with one GPT Image 2 run over 6 minutes.
