Upload an image, call an existing background-removal API, show the result — a thin, honest wrapper, genuinely one of the simplest ideas in this whole library.
Build it
Effort: an eveningRunning cost: $0/mo to start
Why CanICodeThis says Build it
Image upload and a call to an existing background-removal API is a bounded, well-documented integration
A before/after preview with a download button is simple front-end work
No accounts needed if you process and discard images immediately
The parts that'll cause problems
API costs scale with usage, so real traffic needs a pricing or rate-limit plan
Batch processing many images at once adds real queue-management scope
Manual edge touch-up (erase/restore by hand) is a genuine additional editing feature

The build prompt
Build me a background-removal tool: upload an image, send it to an existing background-removal API, show a before/after comparison, and let me download the result. No accounts — process and discard immediately.
