genkiln gives developers access to the best video and image generation models behind a single API key. Instead of juggling multiple vendor SDKs and separate billing accounts, teams call one async REST endpoint to run Veo 3.1, Seedance, Kling, Nano Banana and GPT Image jobs.
Work starts with a single request and is polled until it completes, so long video renders never block a server thread or tie up a worker. Every model publishes its exact per-task price in credits, and the cost is shown before the task runs, so there are no surprise invoices at the end of the month.
Credits are prepaid, never expire, and there is no monthly fee or minimum spend. If a task fails, the credits used for it are refunded automatically to the account. Each model also ships a documented JSON Schema for its input together with clear examples, so integrators can validate parameters locally and catch mistakes before spending anything.
Typical use cases include AI video generation for short-form content, AI image generation for product visuals and thumbnails, and batch API access for automated creative pipelines. The service is built for developers, product teams, agencies and studios that need reliable model routing without long vendor negotiations.
