How this service works
Macro indicators for any country from the World Bank (CC BY 4.0): GDP, GDP growth, GDP per capita, inflation (CPI), unemployment, population, current account, government debt and lending interest rate, with the year, value and unit of each. Country by ISO2 or ISO3 code or exact name; indicator by friendly name or a raw World Bank code. Values lag by one to two years; years with no published value are left out.
Output
Returns a JSON object with a time-series array of annual values (year + value) sorted newest first, the resolved country name and ISO3 code, the indicator's World Bank code and human-readable name with units, the data source string with CC BY 4.0 attribution, and a checkedAt timestamp. Also includes a disclaimer that the data is informational only.
Example use cases
Inflation trend research for investors
“Get me the annual inflation data for the United States going back 20 years — I want to see how consumer prices have moved since 2005.”
GDP growth comparison for emerging markets
“Fetch Brazil's GDP growth rate for the past 10 years so I can see how the economy has been performing decade over decade.”
Government debt analysis for policy report
“Look up Japan's government debt as a percentage of GDP for the last 30 years — I need the full historical series for a policy brief.”
Technical details
Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/econ/indicator?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, multi-year macroeconomic time-series data for a specific country sourced from the World Bank. It is ideal for economic research, financial analysis, compliance reporting, or policy briefs requiring authoritative national statistics. Prefer this over scraped or estimated data sources when World Bank coverage and CC BY 4.0 attribution are acceptable. Choose this over a general web search when you need clean, machine-readable JSON series rather than prose summaries.
Side effects
- Invalid or unrecognized country code/name returns an error
- Unknown or unsupported indicator code returns an error
- Years parameter outside 1–60 range may be rejected or clamped
- World Bank upstream may have gaps or null values for certain country-year combinations
- Some indicators may not have data for all countries (sparse series)
- Payment failure (x402) if USDC balance is insufficient
