How this service works
Daily ECB euro foreign exchange reference rates for 30 currencies (incl. EUR), any base via cross rates, conversion, historical dates (2024-09-24 onward) and time series. Updated daily. Source: ECB (European Central Bank euro foreign exchange reference rates). Reference rates are published around 16:00 CET on TARGET business days for information purposes only; not for transaction pricing. Cross rates are derived via EUR. Also: AI infrastructure price reference data (cloud GPU instance list prices on AWS and Azure, LLM API token prices), refreshed daily. Also: country macroeconomic indicators (GDP, growth, inflation, unemployment, debt, current account, reserves, FDI, population and more) for ~217 economies from the World Bank World Development Indicators (CC BY 4.0).
Output

Example use cases

Technical details
Endpoint
GEThttps://fx-reference-rates.regnotes.workers.dev/v1/macro/rank?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a ranked, cross-country comparison of a specific macroeconomic indicator from World Bank data, especially when filtering by income group or region matters. Prefer it over raw data downloads when you need a ready-made leaderboard or bottom-N list. Not suitable for transaction FX pricing or historical time-series analysis.
Side effects
- Missing required 'indicator' query parameter returns a validation error
- Invalid indicator enum value returns a 400-level error
- Requesting a year before World Bank data coverage returns empty or null results
- Invalid region or income group filter silently returns empty array
- Non-numeric or malformed 'limit' parameter fails schema validation
