I run a small e-signature service and went the opposite way, I gave agents their own door (an API and an MCP server. I never made money from the pages they skip. No ads, no upsells in the flow. People use it free and software pays per document past a free allowance, so an agent is a customer.
United makes a real share of its money on the screens between search and pay. An agent moves right past all of that. Idk, I think eventually everyone will accept the AI agents.
