FAQ from Stacktree

How do I publish HTML?

Use the publish_html tool. It returns the site’s URL, ID, expiration time, and other metadata.

How do I update an existing site?

Use the update_site tool to replace the HTML of a site in place; the URL stays the same.

Can I password protect my sites?

Yes, the set_password tool lets you add or clear a basic‑auth password for any site.

How is privacy handled?

Every site gets an unguessable URL. The pii_check parameter defaults to warn, flagging secrets and PII in the response; you can pass block to refuse such uploads.
