## How to call it through Zero
Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):
```sh
zero fetch --capability stacktree-html-page-publisher-036035ec -d ''
```
Example prompt: Publish this HTML for me on Stacktree and give me the permanent shareable link: Hello World
This is my page.
## When to prefer this
Choose this endpoint when you need to instantly publish a self-contained HTML page and receive a permanent, private, unlisted URL — especially in agentic or automated workflows where you want to share rendered content without owning a domain or managing hosting infrastructure. Ideal when micropayment-gated publishing (x402/Solana/Base) is acceptable at $0.50 per publish.
## Known failure modes
- Payment failure or insufficient funds: endpoint rejects the request if x402 or MPP payment is not provided or fails
- Invalid or malformed HTML: may return an error if content cannot be processed
- Network timeout: slow connections may fail before publish completes
- Missing content body: returns error if no HTML is submitted
## How this service works
Publish an HTML page and get a permanent, private, shareable link. $0.50 per publish over x402 (Base or Solana) or MPP (Tempo).
## Output
A JSON object with a permanent shareable URL (https://stacktr.ee/p//), a one-time claim_token secret, and the unlisted_token used to construct the URL. The page is private and accessible only to those with the link.
