API questions before your first call
- At 1080p, each second costs $0.29 and a minute comes to $17.47 (R$58.46, 976 credits). Each generation runs 3 to 10 seconds.
- Create an account, make a key and send the request to the quote, which charges nothing. The smallest Kling Omni Pro generation costs 49 credits, more than the 15 free ones: use those to try a cheaper model from the catalog.
- First and last frame: two images become the start and the end of the video. From an image: the image you send becomes the first frame. With references: up to 4 images guide the character, product or style.
- No. Buy a credit pack by card, or in reais with Pix from Brazil, and spend it on Kling Omni Pro and every other model with the same key.
- No. The Cut.Pro key calls Kling Omni Pro without a Kling account, with one balance for every model in the catalog.
- Yes. With a CPF or CNPJ and full address in your billing details, the nota fiscal is issued after each payment is confirmed.
