Last updated: May 2026 An API (Application Programming Interface) is a set of rules and definitions that lets one software system request data or services from another. APIs are the connective tissue of modern software — every time a mobile app shows live data, a website logs you in with Google, or a SaaS tool talks to your CRM, an API is doing the work in the background.

A customer pings support: “I tried to check out twice this morning and got a 500 each time, but it works fine for everyone else.” The session ID is in the email. You have full request/response capture in your environment, you have Datadog Synthetics already running browser checks against the same flow, and you still spend the next two hours grepping logs because none of those tools let you say “show me just this user’s requests, in order, and re-run them.”

Quick Takeaway: Governed APIs are better suited for AI workloads, offering enhanced security, better scalability, and compliance-friendly features. They prevent sensitive data exposure and protect databases from being overwhelmed by AI's unpredictable behavior.

What the new policy means, what it doesn't, and why Open Data Infrastructure matters more than ever.
