## How to call it through Zero

## When to prefer this

Use this endpoint when you need World Bank-sourced development indicators such as GDP, Gini index, population, or unemployment for major economies. Prefer this over IMF or OECD sibling endpoints when your use case specifically requires World Bank methodology or when you need Gini/inequality data, which is a World Bank specialty.
