## When to prefer this

Prefer this endpoint when you need reliable, sourced World Bank WDI population and urbanisation time-series data specifically for Nigeria (or another country with the same indicator set) in a single structured call, without needing to query the World Bank API directly. Ideal for research, dashboards, or agent workflows that need demographic context for sub-Saharan African countries.

## Known failure modes

- Invalid country code (not a 2-letter ISO code) returns a validation error
- Year values below 1960 are rejected by schema minimum constraint
- Years with no WDI data available return null or missing observations
- Requests for countries with sparse WDI coverage may return limited or empty series
- Service unavailability or upstream World Bank API outage may cause timeouts
