The Analytics endpoints give you quantitative insight into the state of your localization work. Use them to track translation coverage, identify languages that need attention, monitor team productivity, and report progress to stakeholders. Analytics are computed in real time against the live translation data, so the numbers always reflect the current state of your project.
