Prospolabs is a generative AI media platform. Use frontier image and video models — Seedance, Kling V3 / O3, Veo 3.1, GPT Image 2, Nano Banana, Seedream — through one playground and one API. Pay USD per generation, no tokens or credits to convert.
Send a POST request to /v1/generate with the model id, your prompt, and any model-specific parameters from the dropdowns. We return a generation_id, the output URL, and the exact USD cost charged. Webhook delivery is supported for long-running video jobs.
Pay USD per generation. Each model has its own per-image or per-second rate; the playground shows the live cost as you change settings. Same price for UI and API. Top up your balance from $5 — no subscriptions or tokens.
Twelve to start: Seedance 2.0 (Fast & base), Kling V3, Kling V3 Pro, Kling O3 Pro, Veo 3.1 (Lite, Fast, base), GPT Image 2, Nano Banana 2, Nano Banana Pro, and Seedream 5 Lite. More are added on a rolling basis.
Image generation: 3–15 seconds depending on the model and resolution. Video generation: 30 seconds to 3 minutes depending on duration, model tier, and audio. We expose a webhook for jobs longer than 30s so you don't have to poll.
Top up from $5. At current pricing, $5 covers ~250 Seedream 5 Lite images, ~40 seconds of Veo 3.1 Lite audio video, or any mix across the catalog. There's no subscription and unused balance never expires.
