I love APIs, but as we move towards a more agent-based world, I think we'll see forward-thinking products and platforms offer an interface that's built for agents. Today, we have robots.txt and sitemap.xml support. They provide instructions to webcrawlers. Tomorrow, I can imagine us having an agents.json file on websites that provides a description of how to "talk" to the agent interface and what features are supported.  Kind of like a discoverable REST API. So, agents like OpenAI's Operator could then query that file first to see if there's an agentic interface, and if not, revert back to the less-optimal human-oriented one. What'll be super-interesting is how agents will self-identify who they are and which human they're acting on behalf of -- hopefully, in a verifiable way. Sort of like OAuth for agents. Fun times ahead!
