Image generation by Google imagen4-fast
## Query Task Status
After submitting a task, use the unified query endpoint to check
progress and retrieve results:
**Get Task Details**
Learn how to query task status and retrieve generation results
::: tip[]
For production use, we recommend using the `callBackUrl` parameter to
receive automatic notifications when generation completes, rather than
polling the status endpoint.

The URL to receive generation task completion updates.
Optional but recommended for production use.

information
- Your callback endpoint should accept POST requests with
JSON payload containing results
- Alternatively, use the Get Task Details endpoint to poll
task status

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 hair (slightly faded) and freckled skin, looking
directly and intently into the camera lens with a
hopeful yet slightly uncertain smile. She wears an
oversized, vintage band t-shirt (slightly worn, with
the faintly cracked white text “KIE AI” across the
chest) layered over a long-sleeved striped top, along
with 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.
