API questions before your first call
- At 720p, each second costs $0.36 and a minute comes to $21.84 (R$73.08, 1,220 credits). Each generation runs 3 to 15 seconds.
- Create an account, make a key and send the request to the quote, which charges nothing. The smallest HappyHorse 1.0 generation costs 61 credits, more than the 15 free ones: use those to try a cheaper model from the catalog.
- Text only: the prompt describes everything. From an image: the image you send becomes the first frame. With references: up to 9 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 HappyHorse 1.0 and every other model with the same key.
- No. The Cut.Pro key calls HappyHorse 1.0 without a Alibaba 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.
