POST /v1/projects/{project_id}/photo_uploads: A single-use slot for a front photo larger than a JSON body allows (up to 10 MB, JPEG, PNG or WebP): PUT the bytes to upload_url with their Content-Type within 2 hours, then name the upload in a generation (source.type photo_upload).

POSThttps://api.light-ai.app/v1/projects/{project_id}/photo_uploads

A single-use slot for a front photo larger than a JSON body allows (up to 10 MB, JPEG, PNG or WebP): PUT the bytes to upload_url with their Content-Type within 2 hours, then name the upload in a generation (source.type photo_upload). At most 20 open slots and 100 slots a day per organization (429 photo_uploads_daily). Uploaded originals are working copies: deleted once used or a few hours after an unused slot expires; the generated mockups stay in the project. Test keys get a simulated slot (no upload URL).

Scope	`mockups:write`
Credential	API key: `Authorization: Bearer lai_live_…` (or `lai_test_…`). Partner keys add `Light-AI-Organization`.
Test mode	Works with test keys against simulated test objects.
