Technical details
Endpoint
GEThttps://worldbank-x402.vercel.app/worldbank/compare?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to cross-compare a specific World Bank development indicator across multiple countries at once, rather than querying country by country. Ideal for ranking, benchmarking, or visualizing how nations stack up on a single metric like GDP, life expectancy, or CO2 emissions. Prefer over the single-country endpoint when the user wants a multi-country leaderboard or comparison table.
Side effects
- Invalid or unrecognized indicator code returns an error or empty results
- More than 10 country codes provided returns a validation error
- Invalid ISO2 country codes produce missing entries or errors
- World Bank API unavailable causes 502/503 upstream errors
- Some countries may have no data for the requested indicator, resulting in null values or missing entries
