## When to prefer this

Use this endpoint when you need official World Bank macroeconomic or development data for any country — GDP, population, inflation, unemployment, CO2, and 1,000+ other indicators — especially for country comparisons, market sizing, or economic background research. Prefer it over general web search when you need structured, reliable, time-series numeric data from a canonical international source.

- Unknown or misspelled indicator code returns no data
- Some indicators have gaps for certain years or countries (null values)
