Cheaper Kling 4.0 tier: 720p clips of 3 to 20 seconds with native sound.
Call the Kling 4.0 Flash API through your SamAutomation key — submit a job with the model_id, then poll until it's done. One key for every model, no per-vendor onboarding or separate billing.
Yes. On SamAutomation Kling 4.0 Flash References runs through one endpoint - POST /api/ai/jobs with model_id "kling-4-0-flash-reference" - so you do not need a separate account or key with Kuaishou. You submit a job and poll it until the video is ready.
Kling 4.0 Flash References starts at 62 credits per job at its cheapest settings. Longer clips and higher resolution cost more. Credits come with a plan, and the same key also covers JSON-to-video rendering and every other model.
No. Every render costs credits - 62 at the floor for Kling 4.0 Flash References. Plans bundle monthly credits.
You reach Kling 4.0 Flash References through this API with your SamAutomation key, not through Kuaishou's own app, so that app's sign-up and regional availability are not what gates you. The model's own content rules still apply to what you generate.
Kuaishou publishes the model itself; this page is about calling it as an API alongside every other model on one key, which is a different job from their consumer app.
There is nothing to download. The Kling 4.0 Flash References API documentation you need here is our own reference: one endpoint, one key, and the model_id above. Kuaishou publishes its own docs for the model, but those describe their platform, not this one.
If it is listed on this page it is active on the platform and you can call it today. Model availability moves — makers retire versions and add tiers — so the list here is the current state rather than a promise about next quarter.
You do not need a vendor SDK here. Kling 4.0 Flash References is an HTTP call: POST /api/ai/jobs with your key and model_id "kling-4-0-flash-reference", then poll the job. Any language that can send JSON can drive it, and the request shape is the same for every model on this platform.
The practical questions are the same for every generation service: what the provider may do with what you upload, how long it is kept, and whether it can be used for training. Read that clause before you send client material through any model, ours included. Kuaishou publishes its own terms for the model itself.
That is up to Kuaishou, not to us, and it differs per model and per release. If open weights matter to you, check the maker's own licence. Running it here is renting inference, not getting the weights.
No. The consumer app and the API are separate products with separate limits. Here you call Kling 4.0 Flash References through this platform, so there is no app to install and no second subscription.
Cheaper Kling 4.0 tier: 720p clips of 3 to 20 seconds with native sound. Pick it when that is the job; a cheaper model wins when it is not.
One key for JSON-to-video and every AI model — Kling 4.0 Flash References starts at 62 credits. Documented and ready for your pipeline.
