post https://api.bitmind.ai/oracle/v1/34/get-video-upload-url
Returns a presigned S3 URL that can be used to upload a video file directly to S3, bypassing API payload limits (useful for files larger than 6MB). After uploading to S3, the returned videoUrl can be used with the detect-video or preprocess-video endpoints. The presigned URL expires in 15 minutes and has a 200MB upload limit.
