The ecosystem average is drifting up by 38 points. New protocols and wider adoption are pushing the curve higher; fresh long-tail scans moderate the pace.

Every scan rolls up into four layers. Access leads at 44%; Payments trails at 5% - a 39-point spread. Only 0 of 5 layers clear the halfway mark: agent-readiness today is uneven, not whole. The cheap layers (metadata, discovery) run ahead while the layers that need real engineering (auth, integration) lag behind.

Averaging every scan in a segment ranks industries by agent readiness, and the gap is wide. Commerce Tools leads at 62 - the segments at the top cluster around high-stakes, technical workflows (infrastructure, CRM, auth) where being legible and actionable to agents is fast becoming table stakes. At the other end, Climate & Energy trails at 30, a 32-point spread across the 27 categories we track: the segments at the bottom still feel little external push to open up for agents.

A handful of protocols dominate; most are still rare. Each bar is the share of scanned sites that fully pass that check - llms.txt exists leads at 43%; at the other end, MPP payment protocol sits at just 0.045%.
