Request Example

{
    "input": {
      "prompt": "The photo: Create a cinematic, photorealistic medium shot capturing the nostalgic warmth of a late 90s indie film. The focus is a young woman with brightly dyed pink-gold hair and freckled skin, looking directly and intently into the camera lens with a hopeful yet slightly uncertain smile, she is slightly off-center. She wears an oversized, vintage band t-shirt that says \"Replicate\" (slightly worn) over a long-sleeved striped top and simple silver stud earrings. The lighting is soft, golden hour sunlight streaming through a slightly dusty window, creating lens flare and illuminating dust motes in the air. The background shows a blurred, cluttered bedroom with posters on the wall and fairy lights, rendered with a shallow depth of field. Natural film grain, a warm, slightly muted color palette, and sharp focus on her expressive eyes enhance the intimate, authentic feel",
      "aspect_ratio": "16:9",
      "output_format": "jpg",
      "safety_filter_level": "block_medium_and_above"
    }
