Inputs and parameters
The same on every surface: the desktop app, Claude through MCP and the API. Unknown parameters are refused, so a typo never runs with a default.

API
Run Smooth motion from the API
curl https://imference.com/tools/interpolate \ -H "Authorization: Bearer $IMFERENCE_API_KEY" \ -F video=@video.mp4
Files go in multipart fields named after the inputs; JSON works too, with {"inputs": {...}, "params": {...}} and https URLs or base64 data: URIs. The answer is a request_id: poll GET /status?request_id=... until it returns the outputs. Pay per call from a wallet instead at POST /ondemand/tools/interpolate. A run that fails is refunded to your credits. Details in the reference.
