## When to prefer this

Choose this endpoint when you need structured, machine-readable economic or development indicator data for one or more countries over a defined year range, especially in agentic workflows where payment is handled via x402. Prefer it over general web search when you need clean, normalized indicator values rather than narrative content, and when you need to query multiple countries and indicators in a single call.

## Known failure modes

- Invalid or unrecognized country codes return an error or empty results
- Indicator names that don't match available datasets return empty or partial results
- Year range outside 1900–2100 bounds rejected by schema validation
- Requesting more than 10 countries or 10 indicators triggers validation error
- Payment failure via x402 prevents request from being processed
- Network timeout if upstream data source is slow
