Get an upload URL

Request a one-time presigned URL to upload a video directly to S3, so large files never proxy through the API. After uploading, call Submit a video with the returned storage_key.

POST/api/v4/video-recognition/upload-url/

Request (JSON body)

Field	Type	Required	Description
`filename`	string	Yes	Original filename, including extension. The extension must be one of `.mp4`, `.mov`, `.avi`, `.mpeg`. It is used to validate the type and pin the `Content-Type` on the upload.

curl https://api.slipstreammusic.com/api/v4/video-recognition/upload-url/ \
  -X POST \
  -H "Authorization: Bearer $PARTNER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"filename": "clip.mp4"}'

Response (201 Created)

{
  "upload_url": "https://bucket.s3.amazonaws.com/temp/video-recognition/8f3c...2a_clip.mp4?X-Amz-...",
  "storage_key": "video-recognition/8f3c...2a_clip.mp4",
  "expires_in": 600,
  "content_type": "video/mp4"
}

Field	Description
`upload_url`	Presigned S3 `PUT` URL. Upload the file here within `expires_in` seconds.
`storage_key`	Reference to the uploaded file. Pass this to Submit a video.
`expires_in`	Seconds until `upload_url` expires (default 600).
`content_type`	The exact `Content-Type` header you must send on the `PUT`.

Upload the file

PUT the raw bytes to upload_url, using the exact content_type returned. Do not add an Authorization header to this request, the URL is already signed.

curl "$UPLOAD_URL" \
  -X PUT \
  -H "Content-Type: video/mp4" \
  --upload-file /path/to/clip.mp4

Then start recognition with the storage_key:

curl https://api.slipstreammusic.com/api/v4/video-recognition/ \
  -X POST \
  -H "Authorization: Bearer $PARTNER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"storage_key": "video-recognition/8f3c...2a_clip.mp4"}'

⚠️

Send the Content-Type on the PUT exactly as returned in content_type. It is pinned at signing time, so a mismatched header is rejected by S3.
