Google Flow API v1
November 17, 2025 (December 23, 2025)
This is the experimental API for Google Flow by Google Labs.
Google Flow creates cinematic AI clips with Veo, images with Imagen 4, Nano Banana / Gemini 2.5 Flash Image, and Nano Banana Pro / Gemini 3 Pro Image.
Use any Google AI subscription or even free account for image generations. Use a Google AI Ultra $125/m special subscription plan for Veo 3.1 Fast $5cents/video and Veo 3.1 Quality $50cents/video generations. Veo 3.1 Fast Relaxed is available for Ultra subscribers with no credit cost but lower generation priority.

Captcha Requirement: Image and video generation (POST /images, POST /videos) requires a third-party reCAPTCHA solving service. Configure your API keys via POST /accounts/captcha-providers. Each generation attempt incurs a captcha cost of $2.5-$3.0 per 1,000 solves depending on the provider. We have thoroughly tested EzCaptcha and recommend it as the primary provider. See Setup Google Flow - Captcha Providers for details.
High Volume Usage: If you expect high volume of calls, you will need to set up a proxy for POST /images and POST /videos. Prefer residential proxy with sticky sessions and 15-30 minute IP rotation. Google returns 403 errors for high volume calls from a single IP. See Setup Google Flow - Configure Proxy for details.
