Compatibility

apimart/OpenAI-style requests work too:

  • model: nano-banana-2, google/nano-banana-2, nano-banana-2-ext, gemini-3.1-flash-image-preview, gemini-3.1-flash-image-preview-official.
  • size instead of aspect_ratio: a ratio (16:9) or exact pixels (1600x1200) — we use the closest supported ratio.
  • Photos can go in image_urls, image_input or input_urls. Parameters may also be sent at the top level of the body, without the input wrapper.
  • resolution in any case (1k, 2K); jpg and jpeg are the same. n must be 1 (one image per request).
  • nsfw_check, official_fallback, google_search are accepted but do not change the result.

Result

Same as any task: call recordInfo or receive a callback. Image links are in resultJson (kept for 24 hours).

Upload your photos via files/upload or pass any public https links.
