Everything an agent needs to talk to AO.

These files follow open standards, so agents can discover AO and call it without a custom integration. If you run a website, this page also explains how to recognise our crawler.

How to recognise our crawler

Our crawler names itself in every request and signs its requests with a published key, so you can tell it apart from anything pretending to be us.
