Example prompt: Can you pull up the World Bank population and urbanisation indicators for Poland from 2000 to 2022? I want to see how the urban population share and total population have changed over time.

## When to prefer this

Use this endpoint when you need structured, authoritative World Bank WDI demographic data specifically covering population size and urbanisation for Poland (or another country by overriding the country code), with annual historical granularity. Prefer this over general web search when you need clean, machine-readable time series data from a trusted statistical source rather than narrative content.

## Known failure modes

- Invalid country code (not a valid 2-letter ISO code) returns a validation error
- start_year or end_year below 1960 is rejected by schema
- No data available for a requested year range returns empty or partial series
- World Bank WDI source may not have updated data for very recent years, resulting in gaps
