A starting point.
Separate a foreground subject from its background. Keep the original and, when needed, request the mask so you can inspect or refine the selection.
Before you publish.
Check hair, transparent objects and low-contrast edges over different backgrounds. Foreground refinement can change edge detail; compare it with the original before compositing.
Review the quote before running. A failed generation releases its reserved credits. Download the results you want to keep; stored media is retained for 30 days.

Inputs and settings
Provide image_url and select model and operating_resolution in the studio. These controls affect how the source is processed rather than describing a new scene.
Use output_mask to request the selection mask. Choose output_format and review refine_foreground before submitting.

From quote to result.
Request a credit quote for your input and settings before submitting a generation. A sample output or the price of another model is not a quote for your request.
Follow the generation workflow, then poll the job for its status and result. The API and studio use the same balance.
