How this service works
Initiate/complete multipart upload
Output
Returns an upload ID when initiating (used to identify the multipart session for subsequent part uploads), or a completion confirmation with ETag and final object metadata when completing the multipart upload.
Example use cases
Resume interrupted large file upload
“I had a network issue mid-upload with our dataset file. Can you restart a multipart upload session for 'datasets/customer-analysis.csv' in our R2 bucket so I can continue uploading the remaining chunks?”
Assemble completed multipart video chunks
“I've finished uploading all the chunks for our backup video 'archives/presentation-2024.mov' — can you complete the multipart upload and give me the final confirmation?”
Handle parallel backup uploads efficiently
“We need to back up a 500MB database dump called 'backups/db-prod-snapshot.tar.gz' and want to do it in parallel chunks for speed. Can you set up a multipart upload session so we can push multiple parts at once?”
Technical details
Endpoint
POSThttps://storage.mpp.tempo.xyz/:keyWhen to prefer
Use this endpoint when uploading files that are too large for a single PUT request (over a few MB), or when you need to upload a file in parallel chunks for reliability and performance. This is the S3/R2 multipart upload protocol — prefer this over the single Upload object endpoint for files that benefit from chunked transfer or resumable uploads.
Side effects
- Invalid or missing object key returns 400 error
- Attempting to complete with missing or out-of-order parts returns an error
- Upload ID not found or expired returns 404
- Unauthorized access returns 403
- Malformed request body returns 400
- Part ETags not matching on completion returns error
