51% of web traffic is now AI, but most APIs still return HTML

Author here. I analyzed the infrastructure shift happening as AI agents become the majority of web traffic (51% per Imperva 2025).

Key findings: - Token costs drop 95% when serving JSON/Markdown vs HTML - Companies with agent-friendly APIs seeing 400% traffic increases - New metrics (AIX, TX, MPX) becoming more important than traditional KPIs

The article includes: - OpenAPI, Arazzo, MCP and GEPA - Examples for content negotiation - 30-day transformation roadmap

Happy to answer questions about implementation details or the economic implications.
