Show HN: An open URL format for AI agents to report status to humans

AgentDisplay has launched an open URL format that lets AI agents report status to humans via a simple link, requiring no SDK, API key, or signup. The service, available at agentdisplay.ai, uses a UUID as the credential and offers free, $9/month, and $39/month tiers, with security measures that drop sensitive parameters like token, key, and secret.

One URL. Your agent posts to it, you read it at a glance. No SDK, no API key, no signup. agentdisplay.ai/{uuid}?agentname=Deploy Bot&message=Build passed&status=running Works with anything that can fetch a URL — Desktop, phone, or a TV on the wall. Nothing to install and nothing to sign up for. Send the link to whoever kicked the agent off, and turn on alerts so you only have to look when something needs you. Three keys mean something specific. Every other query param becomes a stat card — no registration, no schema, no waiting for us to add it. | Key | Meaning | |---|---| | agentname | Names the agent posting — one URL can host a whole team, each agent under its own name | | message | Appended to the message feed | | status | One of: . Anything else renders grey and unstyled. | | | Anything else becomes a stat card — whatever your agent wants to show | The UUID is the credential. It is unguessable, and it works like a Google Docs share link: anyone holding it can read and write, and rotating it is how you revoke. So treat a display as public — don’t post secrets to it. And because an OAuth callback or a checkout redirect will eventually try to post one for you, params named token , key , secret , jwt , session and their relatives are dropped before they are ever stored.
