- Prices in US dollars. Settings where KreatorFlow does not cost less are not listed.
- Kie.ai is shown at its credit price without a video input, converted at $0.005 per credit. Bonus credits on some top-ups are left out, like every promotion. Its Seedance 2.0 Fast price changed the day an offer ended, so Fast is not compared until that price has held.

Switching from Kie.ai
What changes in a Seedance request when you move it from Kie.ai to the KreatorFlow API. Kie.ai's side is described as its own API docs show it, with the link below.
- Send the job to POST https://kreatorflow.ai/v1/videos instead of POST https://api.kie.ai/api/v1/jobs/createTask.
- Authenticate with Authorization: Bearer $KREATORFLOW_API_KEY, a key from the developer console, instead of Authorization: Bearer $KIE_API_KEY.
- Name the model in the body: "kreator-video-seedance-2" for Seedance 2.0, "kreator-video-seedance-2-5" for Seedance 2.5.
- Move the fields out of "input": prompt, resolution, duration, aspect_ratio and generate_audio go at the top level of the JSON body.
- Use a clip length of 4, 5, 6, 8, 10, 12 and 15 seconds; "-1" for an automatic length is not accepted.
- Send generate_audio: true if you want audio: it is on by default there and off by default here.
- Replace GET https://api.kie.ai/api/v1/jobs/recordInfo?taskId={taskId} and callBackUrl with webhook_url (signed with X-KreatorFlow-Signature) or GET /v1/jobs/{job_id}, and add an Idempotency-Key header so a retried request returns the same job.

FAQ
Is the KreatorFlow API cheaper than Kie.ai for Seedance?
At every setting in the table, yes: Seedance 2.0 at 480p, 720p, 1080p and 4K, and Seedance 2.5 at 720p and 1080p, between 15% and 52% less per clip. For example, Seedance 2.0 at 720p is $0.110 per second on KreatorFlow against $0.205 on Kie.ai: $0.55 against $1.03 for a 5-second clip. Settings where Kie.ai costs the same or less are not listed.
Is it the same Seedance model?
Both APIs sell ByteDance's Seedance under that name. KreatorFlow is an official partner of BytePlus, a ByteDance company.
How does KreatorFlow API billing work?
You buy prepaid tokens (1 token = $0.05, top-ups from $20). A video job costs its per-second rate times the clip length, rounded to the next whole token. Tokens reserved for a failed job are released.
How do you turn Kie.ai credits into dollars?
At the value Kie.ai publishes on its pricing page: one credit is $0.005. Its per-second credit price at each resolution times 5 seconds gives the per-clip price in the table. Bonus credits on some top-ups are not counted, as with every other promotion.
Do I keep the input object and callBackUrl from Kie.ai?
No. Kie.ai nests the parameters under "input" and takes callBackUrl next to it. On KreatorFlow, prompt, duration, resolution, aspect_ratio and generate_audio sit at the top level of the JSON body, and the callback is webhook_url, signed with X-KreatorFlow-Signature. Clip lengths are 4, 5, 6, 8, 10, 12 and 15 seconds; -1 for an automatic length is not accepted.
Do I still poll for results?
You can: poll GET /v1/jobs/{job_id} the way you poll recordInfo on Kie.ai. Or pass webhook_url and receive job.completed, job.failed, job.canceled or job.blocked as a signed callback.
Is KreatorFlow part of Kie.ai?
No. KreatorFlow is an independent company with no connection to Kie.ai.
