How this service works
Uploads files or assets to Stable Studio for a 10,000 USDC-equivalent fee.
Output
Returns a Vercel Blob client token for authenticating the upload, the destination pathname for the file, an expiry timestamp for the session, and an example curl command demonstrating how to perform the actual file upload.
Example use cases
Secure media asset uploads for content platform
“I need to let users upload their profile pictures and cover images to our platform. Can you create signed upload sessions for each file so they get the authentication token and exact destination path, plus show them how to complete the upload with curl?”
Batch file processing with temporary credentials
“We're building a document processing pipeline where users submit PDFs in bulk. Generate signed upload sessions for each file they need to upload, give us the tokens and expiry times, and include the curl examples so our backend can handle the uploads securely.”
Mobile app file upload without API keys
“Our mobile app needs to upload user-generated videos to cloud storage, but we don't want to embed API keys in the app. Can you create a signed session with a short-lived token and pathname for each video upload, then show us the curl command our frontend should execute?”
