# Generate Nail Video Route

`POST /api/nail-video/generate`

## Request

- Base URL: `https://api.tintin-x.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.tintin-x.com/api/nail-video/generate`
- Auth: HTTP bearer

Charge + enqueue one nail-video job (1 hand → `num_videos` MP4 variants).

## Request body

- NailVideoGenerateRequest: POST `/api/nail-video/generate` body. Replaces the nail tips in a stored TEMPLATE VIDEO (resolved server-side from `template_id`) with the nails shown in the uploaded `source` image, via fal Seedance. The client never supplies a raw video key — only the catalog `template_id`. Async like try-on / lifestyle: returns a `JobCreateResponse`; the N output MP4s land in `hands[0].candidate_video_urls`, polled via `getJob`.
