Quick Answer

  • Use POST /v1/images/generations with the Nano Banana 2 model id documented by ToAPIs.
  • Supports prompt generation and reference_images for ad, e-commerce, social, and batch creative assets.
  • The workflow is async: submit the task, receive a task id, then poll the image task status endpoint.

  • At the ToAPIs 1K listed rate of $0.025 per image, a $10 top-up is roughly 400 additional 1K images; at the 4K listed rate of $0.040 per image, it is roughly 250 4K images.
