What will you Discover
Global API latency dropped by 53% year-over-year.
The average load time fell from 695ms to 322ms as optimization became the primary engineering KPI. This shift is driven by AI agents, where high latency causes timeouts and operational failures rather than just poor UX.
Nearly half of all API traffic is completely anonymous.
Despite Zero Trust initiatives, 47% of APIs still process requests without any authentication, and 42% of traffic remains unencrypted HTTP. Basic security hygiene is lagging significantly behind raw performance gains.
API sprawl is finally shrinking as governance tightens.
The percentage of "Zombie" endpoints dropped from 36% to 17%. Driven by regulatory pressure and cost controls, organizations are actively deprecating legacy infrastructure rather than letting it accumulate as technical debt.
