# Upload one input image as an Asset

POST https://api.morphiaone.ai/v1/assets
Content-Type: image/jpeg

Send raw JPEG, PNG or WebP bytes as the request body with the matching
`Content-Type`. No `Idempotency-Key`: an upload is not deduplicated, and uploading
the same bytes twice creates two assets. The asset is owned by the caller's
environment and expires at `expires_at`. Metadata (EXIF, XMP, IPTC) is removed and
pixels are rotated to their displayed orientation before the asset is stored, so
`width` and `height` are the displayed dimensions.
