genkiln

genkiln gives developers one API key for Veo 3.1, Seedance 2.0, Kling 3.0, Nano Banana, and GPT Image, so you don't need a separate account for each model. Key features: • Video and image generation through one async REST API • Exact credit cost shown before every task runs • Automatic refunds for failed or canceled tasks • Signed webhooks and idempotency keys • JSON Schema for every model's inputs • Usage console and credits that never expire Switching models means changing one field in the request, not rewriting your integration. Each task reports its cost up front, and you're charged only when it succeeds. Credit packs start at $10 with no subscription or monthly fee, so you pay only for what you generate. Signed webhooks notify your backend when tasks finish, and idempotency keys prevent duplicate charges when requests are retried. The JSON Schema for each model lets you validate inputs before submitting, and the usage console tracks spending and task history. Results are kept on the CDN for 30 days. Built for developers and product teams adding video or image generation to apps, content pipelines, or internal tools. It suits prototyping with pay-as-you-go pricing, and it also works for production systems that need predictable costs and reliable refunds.
