Why reAPI
Image-to-video that holds identity

Native synchronized audio

Simple per-second pricing
Grok Imagine Video 1.5 bills per second by resolution, with no subscription. The cost scales linearly with the duration parameter, and failed jobs refund automatically — you only pay for clips that succeed.
