## When to prefer this

Choose this endpoint when you need structured, pre-packaged World Bank WDI economic size and growth data for Belgium (or another country via override) without querying the World Bank API directly. Ideal for agents that need reliable, curated macroeconomic time series with minimal setup, especially when comparing Belgium to peer countries using sibling endpoints for Ireland, Israel, India, etc.

## Known failure modes

- Invalid country code (not a 2-letter ISO code) returns a validation error
- Year range outside 1960–present may return empty or partial data
- World Bank source data lag may mean recent years have no observations
- Payment failure (insufficient USDC balance) blocks the call
