## 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-publish-bae84725 -d '<json body>'
```

Example prompt: Take this HTML report I just generated and publish it to a permanent private link using Stacktree — pay the $0.50 fee and give me back the URL and claim token.

## When to prefer this

Choose this endpoint when an agent has generated HTML content (reports, specs, dashboards, editors) and needs to share it via a permanent, private URL with zero setup — no account, no API key, no human approval. Ideal for one-off publishing tasks where the $0.50 per-page cost is acceptable and privacy (unguessable URL) matters more than discoverability.

## Known failure modes

- Payment not included or malformed — 402 Payment Required with instructions
- HTML body missing or empty — 400 Bad Request
- Payment token invalid or already used — 402 or 400 error
- Service unavailable — 503 with retry guidance

## How this service works

Stacktree: host generated HTML as a live, shareable web page on a permanent, private, unguessable link ($0.50). POST any HTML (a report, dashboard, landing page, static site, or any page an agent produced) with payment; we return the URL and a one-time claim token. No account, no key, no human in the loop. The paying wallet can update the page free at the same URL, and a deleted page is restorable for 30 days.

## Output

Returns the permanent, unguessable URL where the HTML page is hosted, plus a one-time claim token that can be used to manage or transfer ownership of the page.
