Publish an app YOU own, on a paid plan: on Free an app stays private and this answers 402 plan_required with the upgrade link. Two ways to publish: "public" gives it a tile in the autario app store under Community apps, next to AI Visibility 360 and the World Bank and FRED data surfaces, plus a public URL, "unlisted" gives it only the URL, so anyone you send the link to can open it and nobody else finds it. Every publish runs a content check first and refuses, naming the rule and the line, an external script, an embedded frame, a form posting elsewhere, a redirect, an advertising or affiliate link, hidden text, or text aimed at AI agents in the name, tagline or manifest. A public listing additionally needs the app hosted on autario (upload_app_bundle) and passes ONE AI content review per content version, synchronously: a block returns the reasons (edit the app and publish again), review_unavailable means try again later. Returns public_url. Viewers read data through autario.js with their own role: a stranger sees public catalog data only, a team member the owner invited to the app (Account > Team) sees the datasets the app declares. Note that a published app is deliberately NOT search-engine indexed; only autario can put a community app into the sitemap. Use it when the user says the app is ready to share. unpublish_app reverses it and is never refused.
