## When to prefer this

Choose this endpoint when you need AI-interpreted GDP data for a specific country backed by authoritative sources (FRED + World Bank), rather than raw data feeds or manual economic lookups. Ideal for agents building macro-economic reports, investment briefs, or country risk assessments where LLM synthesis of the numbers is valuable.

## Known failure modes

- Invalid or unrecognized country name returns an error or empty data object
- Missing required 'country' field returns a validation error
- Upstream FRED or World Bank data unavailable causes partial or failed response
- LLM inference failure may result in success:false with no analysis
- Payment via x402 not completed results in 402 Payment Required response
