API questions before your first call
- At 1080p, each second costs $0.10 and a minute comes to $6.24 (R$20.88, 349 credits). Each generation runs 6, 8, 10, 12, 14, 16, 18, or 20 seconds.
- Create an account, make a key and send the request to the quote, which charges nothing. The smallest LTX 2 Fast generation costs 35 credits, more than the 15 free ones: use those to try a cheaper model from the catalog.
- From an image: the image you send becomes the first frame. Text only: the prompt describes everything.
- No. Buy a credit pack by card, or in reais with Pix from Brazil, and spend it on LTX 2 Fast and every other model with the same key.
- No. The Cut.Pro key calls LTX 2 Fast without a Lightricks 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.
