# Upload Visual Asset

POST https://api.loreos.app/v1/characters/{slug}/visual-assets
Content-Type: multipart/form-data

Upload a visual asset (identity / wardrobe / accessory / …) for a character.

Upload an ``identity`` asset FIRST — it anchors every generated selfie and is
activated immediately. Other categories are rejected (409) until an active
identity exists. Stored in object storage; the response carries the servable
URL. App-scoped (404 if the slug is not owned by the caller's app).

Reference: https://docs.loreos.app/api-reference/visual-assets/upload-visual-asset
