Overview
useapi.net Google Flow API v1 is an experimental REST interface for operating Google Flow through a user's own account. It supports cinematic AI video and image generation without requiring a Google Cloud project or Gemini API key.
Requests select a model through the model field, allowing an integration to target different video or image capabilities.
Models and capabilities
- Veo 3.1 Fast, Quality, and Lite support text-to-video and image-to-video generation.
- Omni 1.1 Flash supports audio-native video with voices, characters, start and end frames, video editing, and clips at 360p or 720p.
- Nano Banana 2 Lite, Nano Banana 2, and Nano Banana Pro provide image generation.
Omni 1.1 Flash produces clips up to 10 seconds according to the service documentation. Nano Banana 2 Lite is the default image model and is available across Google AI plans.
Account and plan requirements
Image generation works with any Google AI plan, including a free account. Video generation requires a paid Google AI subscription and consumes the Flow credits supplied by that plan.
The service uses the account's own Flow allowance rather than the official Gemini API's per-call billing model. Google controls the underlying allowances, so generation capacity can vary with demand and is not guaranteed.
Pricing structure
useapi.net lists a flat service fee of $15 per month in addition to the user's Google AI plan. Plus, Pro, and Ultra plans provide different monthly Flow credit allowances, while image generation is included with the applicable account access.
Veo Fast, Quality, and Lite consume different credit amounts per generation. A lower-priority Veo 3.1 Lite queue and image generation may use free workload allowances on eligible plans, while credit-metered video volume remains bounded by monthly Flow credits.
