SLA (Experience)

Require that every API published for consumers carries a clear service level agreement stating its uptime target, expected performance, support commitments, and what happens when we fall short. I push for explicit SLAs because a promise you will not write down is a promise you do not really mean, and consumers cannot build a serious business on vague assurances. Publish the numbers in the portal, back them with real monitoring and a status page, and be honest when the tier is best-effort. A well-defined SLA is where an API stops being a hobby and becomes something people can depend on.
