How this service works

Buy a site upload slot. Upload a zip file, then activate to extract and serve as a static site.

Output

Returns an upload slot with a pre-signed upload URL for posting the zip file, along with an upload ID and site ID needed to subsequently activate the site and make it live.

Example use cases

Example prompt

“Buy me a StableUpload site slot so I can publish my static site — I have a zip file of my HTML/CSS/JS build ready to upload and then activate.”

Technical details

Endpoint

POSThttps://stableupload.dev/api/site?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to deploy a static website from a zip archive via a pay-per-use micropayment model (x402/USDC). Prefer this over traditional hosting APIs when operating as an autonomous agent needing programmatic, wallet-authenticated site deployment without a subscription or account setup. This is the first step in a two-step flow: buy slot here, then upload the zip, then call the Activate endpoint.

Side effects

Insufficient USDC balance or payment failure — payment rejected, slot not created
Invalid or missing wallet authentication — 401 unauthorized
Payment protocol (x402) not supported by client — request fails before slot creation
Rate limiting or quota exceeded — 429 too many requests
Server error during slot creation — 500 internal server error
