## When to prefer this

Choose this endpoint when you need standardized, World Bank-sourced nominal GDP per capita in current US dollars across a broad set of countries (200+ economies) with consistent provenance. It is ideal for agents performing country income tiering, cost-of-capital modeling, or sovereign risk assessments that require the NY.GDP.PCAP.CD indicator specifically. Prefer it over general-purpose web search or other economic APIs when you need a structured, machine-readable response with clear data lineage back to the World Bank.

## Known failure modes

- Invalid or unrecognized country name returns empty result or error
- Date range outside World Bank data availability returns no data
- Malformed date string causes request failure
- Country code ambiguity (e.g. abbreviations vs full names) may yield unexpected results
- World Bank upstream API downtime propagates as error response
- Missing required fields (country, date) may cause bad request error
