Example use cases

E-commerce product photo cleanup

“Take this product photo and swap the background to a clean studio gray — I need it to look like a professional still shot for our online store listing.”

Brand-color background for marketing asset

“Replace the background on this product image with our brand color #1A73E8 so it matches our marketing materials — here's the base64-encoded JPEG.”

Batch-ready single image prep

“I have a product JPEG that needs a white #FFFFFF background instead of the cluttered original — can you process it and give me back the clean PNG?”

When to prefer

Choose this endpoint when you need a quick, pay-per-use background replacement on a single product image without setting up an API key or subscription. Ideal for e-commerce agents that need studio-quality solid-fill backgrounds (gray or a specific brand hex color) and want a verifiable SHA-256 receipt per operation. Prefer this over general image editing APIs when simplicity, micropayment pricing, and auditability matter.

Side effects

Image exceeds 256 KiB decoded size — returns error indicating payload too large
Invalid base64 encoding — returns malformed input error
Invalid hex color format for fill parameter — returns validation error
Payment not provided or insufficient — returns 402 Payment Required
