POST /api/v1/uploads — get a signed URL, PUT a local video file (MP4, MOV or WebM, up to 100MB) to it, then pass the returned video URL to /upscale.

If your video isn't at a public URL, upload it first. Uploading takes two requests: ask us for a signed upload URL, then send the file straight to storage with PUT.

POST https://videoupscaler.co/api/v1/uploads

Request

`content_type`	string	Yes	`video/mp4`, `video/quicktime` or `video/webm`

For files over 100MB, host the file yourself and pass its URL to /upscale (up to 500MB).

`upload_url`	Where to `PUT` the file. No `Authorization` header is needed; the URL itself is the permission.
`headers`	Send these headers with the `PUT`. `Content-Type` must match what you declared.

`max_bytes`	The upload is rejected if the file is bigger than the `size` you declared.
`expires_at`	The upload URL works for 1 hour.

A successful PUT returns 200 with {"video_url": "…"}.

Notes

Requesting an upload URL is free, but needs a credit balance of at least 1 credit.
Uploaded files are kept only for processing and may be deleted after 7 days.
