Why Runcrate

Built for production. One key, one balance.

  • Priced before it runs

    Mode, audio and length set the price. The API reads them from the request and refuses one that matches no listed price, with the allowed values, before anything is charged.

  • Billed for the seconds made

    A finished clip is settled to the seconds Kling made, and a job that fails is refunded in full, with nothing to claim.

  • Image, audio and video in

    Start and end frames, reference videos, an audio file for an avatar: each is a plain JSON field on the same /v1/videos request.

  • No Kuaishou account

    Call Kling with a Runcrate API key, on the same balance as chat, image and speech models and GPU instances.
