## When to prefer this

Use this endpoint when you need structured, multi-year historical GDP data for a specific country in current USD from a reliable official source (World Bank). Prefer this over general web search when you need machine-readable annual GDP series for macroeconomic analysis, country comparisons, or financial modeling. Best suited for single-country lookups by ISO code rather than bulk cross-country queries.

## Known failure modes

- Invalid or unrecognized ISO country code returns an error or empty result
- Country not covered by World Bank data may return null values or empty array
- Missing ?country= parameter may return a 400 or default error response
- Cloudflare tunnel downtime may cause intermittent 502/503 errors
- World Bank data lag may mean most recent year is unavailable or null
