How this service works
Get a short-lived presigned URL to download an artifact's bytes (the latest version, or version_id). Returns {url, method, expires_at, version_id}. Costs $0.005 in USDC. No signup: a wallet's first payment creates its account and a default project; the same wallet later reaches the same files.
Output
A JSON object containing: a short-lived presigned URL (url) to download the artifact bytes via HTTP, the HTTP method to use (method), the expiry timestamp (expires_at), and the resolved version_id of the artifact served.
Example use cases
Download pipeline output artifact
“Fetch me a download link for artifact f7e21d09 from Artefaktum — I want to grab the latest output file from my ML pipeline run.”
Retrieve specific artifact version
“I need to download version v_abc456 of artifact 9d3c1b78 from Artefaktum so I can compare it with the current build.”
Access artifact in automated workflow
“In my data pipeline, once processing is done, pull a temporary download URL for artifact 3af8e120 from Artefaktum so the next step can read the file bytes.”
Technical details
Endpoint
GEThttps://api.artefaktum.dev/v1/artifacts/:artifact_id/download?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to actually download or stream the binary content of a stored artifact from Artefaktum. It is the correct choice when you have an artifact_id and need the raw bytes or a URL to pass to a downstream system. Prefer this over metadata-only endpoints when the goal is file retrieval rather than inspection of artifact properties.
Side effects
- artifact_id not found — 404 error if the artifact does not exist or belongs to a different wallet
- version_id not found — 404 if the requested specific version does not exist
- expired artifact — artifact may have passed its 30-day retention window
- insufficient USDC balance — payment of $0.005 USDC required per call; failure if wallet has insufficient funds
- presigned URL expiry — the returned URL is short-lived and will reject requests after expires_at
- run_id mismatch — if the specified run_id does not match any version, an error or empty result may be returned
