# Upscale Image

`POST /media/upscale`

## Request

- Base URL: `https://api.moda.app/v1`
- URL: `https://api.moda.app/v1/media/upscale`
- Auth: HTTP bearer

Deterministic super-resolution, 2x or 4x (metered provider call).

An image with real transparency is routed to the alpha-preserving engine,
which renders 4x only: `scale=2` on such an image is rejected with 422 and
a message naming both ways forward. Everything else accepts either factor.

Transparency is detected by reading the image, and that read has a size
ceiling: above ~24 megapixels the alpha channel is left unread and the
image takes the ordinary route, which flattens it. Both factors stay
available there. Flatten such a source yourself if its transparency
matters.
