How this service works

Generative AI platform for images, 3D models, and audio — text-to-image, editing, upscaling, and more.

Output

Returns a JSON object with a `data` field containing the composited and relighted image (typically as base64 or a reference), along with payment settlement details showing the USDC amount charged, and a request ID with a status URL for async polling if needed.

Example use cases

E-commerce product background swap

“I have a product photo of a white coffee mug and I want the background replaced with a cozy rustic kitchen scene. Apply lighting from above at strength 0.7 and export as a JPEG.”

Professional headshot background replacement

“Can you take this headshot photo and swap the background with a blurred modern office interior? Light should come from the right at 0.6 intensity, and save it as a PNG.”

Automotive marketing composite

“I need this car photo placed in front of a dramatic mountain sunset — describe the foreground as a red sports car, background as golden-hour mountains, lighting from the left at full strength, and return a webp.”

When to prefer

Choose this endpoint when you need to both replace a background and apply directional relighting to the subject in a single API call. It is ideal for product photography automation, e-commerce image pipelines, and portrait editing where consistent lighting across composited scenes is critical. Prefer this over a plain background-removal endpoint when lighting coherence between foreground and background matters.

Side effects

Missing subject_image results in a 400 validation error
Invalid output_format value (not jpeg/png/webp) returns a schema validation error
Light source direction outside allowed enum (left/right/above/below) causes rejection
Malformed or inaccessible image URL for subject_image or background_reference causes processing failure
Payment failure or insufficient USDC balance causes a 402 Payment Required response
Seed value out of acceptable range may be ignored or cause an error
Network timeout if image processing takes longer than expected
