How this service works
Upload a static website. Returns the live URL. Caller wallet is stamped as the slug owner; owners can edit/delete or attach custom domains via the other routes.
Output
Returns a JSON object with the live public URL of the published site, the slug portion of the URL, the owner wallet address, content size in bytes, the TTL in hours and human-readable form, and an ISO 8601 expiration timestamp plus an operational note about how to refresh or extend the TTL.
Example use cases
Instant landing page for product launch
“Take this HTML and publish it as a live webpage with the slug 'acme-launch' — it should stay up for 60 days: <!DOCTYPE html><html><body><h1>Acme is here!</h1><p>Sign up for early access.</p></body></html>”
Temporary event invite page
“Host this HTML for me as a short-lived page — use the slug 'summer-party-2025' and set it to expire in 48 hours: <!DOCTYPE html><html><body><h1>You're Invited!</h1><p>Saturday, July 12th, 7pm.</p></body></html>”
Markdown documentation page
“Publish this Markdown content as a live webpage with the slug 'api-docs-v2' and keep it up for 180 days: # API Docs
## Getting Started
Welcome to version 2 of our API.”
Technical details
Endpoint
POSThttps://host.withzero.ai/run?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to instantly publish HTML, Markdown, or plain text as a live public webpage without managing servers, DNS, or deployment pipelines. It's ideal for ephemeral or semi-permanent content (30 minutes to 180 days) where you want ownership tied to a wallet address and the ability to later update, delete, or attach a custom domain. Prefer it over general cloud storage for use cases where a human-readable live URL matters and content needs to be browser-accessible.
Side effects
- Content missing or empty — required 'content' field not provided
- Content too large — exceeds 2,000,000 character maximum
- Slug already taken by another owner — returns conflict error
- Slug format invalid — must match ^[a-z0-9-]+$ and be 3–64 characters
- TTL out of range — must be between 0.5 and 4320 hours
- Unauthorized wallet — caller not authenticated or wallet not stamped
- Server or storage error — upstream R2 or hosting failure

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
