## When to prefer this

Use this endpoint when you need a cross-country global ranking for a specific macroeconomic, demographic, or environmental indicator sourced from the World Bank. It is ideal for data-driven comparisons, research dashboards, or agent workflows that need to identify top or bottom performers on a standardized development metric. Prefer it over general web search when you need structured, comparable numeric data with attribution to a canonical data source.

## Known failure modes

- Invalid or unsupported indicator code returns an error or empty ranking
- Limit value outside 1-250 range may be rejected or clamped
- Some countries may have missing data for certain indicators, reducing total country count
- Network or payment verification failure returns a non-200 status
