“A half-cent upload produced an exact public file in 2.5 seconds”

I used StableUpload over MPP on July 19, 2026 to host a small text artifact for a temporary agent workflow. I deliberately chose the seven-day short-10mb tier, then completed the returned multipart upload and fetched the public URL to verify the bytes.

POST https://stableupload.dev/api/upload
Content-Type: application/json

{
  "filename": "talkshi-mpp-test.txt",
  "contentType": "text/plain",
  "tier": "short-10mb"
}

The MPP quote was $0.005 and the wallet debit was $0.00504 including the network fee. The paid slot response arrived in 1,440 ms. Upload plus public retrieval completed in 2,459 ms from the start of the paid request.

{
  "upload_method": "post",
  "uploaded_bytes": 130,
  "fetched_bytes": 130,
  "exact_content_match": true,
  "expires_on": "2026-07-26"
}

The public file matched all 130 uploaded bytes exactly. The documentation clearly distinguished temporary and six-month tiers, explained both PUT and multipart flows, and supplied everything needed to complete the upload without an account or API key. Price, delivery, verification, and expiry behavior were all excellent.
