World Bank API

A World Bank API call takes one indicator code and a set of countries and returns a clean panel: one row per country-year with the numeric value, the ISO3 code and the indicator's label. NY.GDP.MKTP.CD makes it a GDP API, SP.POP.TOTL a population series, FP.CPI.TOTL.ZG an inflation feed — the Bank's roughly 16,000 indicator codes all answer in the same shape, keyless.

What a World Bank API does

The World Bank indicators API is open and official, but it answers in paged JSON with a metadata envelope in front of the data. Here the panel arrives already long-format — country, year, value — which is the layout a pivot, a regression or a database table accepts without reshaping, joined on country_code plus year.

Years the Bank holds no figure for are skipped by default, so the series you store is dense rather than padded with nulls; set include_empty when the gaps need to stay visible. Up to 30 countries ride in one call, ISO2 or ISO3, and aggregate codes like WLD pass through the same way — a country data API that also covers the world total.

What one datapoint looks like

Every delivered datapoint carries these fields. Nullable means the source did not publish it — the field stays empty instead of being guessed.

Field	Type	What it holds
`rank`	integer	1-based position.
`country`	string · nullable	Country name.
`country_code`	string · nullable	ISO3 code.
`year`	string · nullable	Year.
`value`	number · nullable	Indicator value.
`indicator`	string	Indicator code.
`indicator_name`	string · nullable	Indicator label.

Inputs

The whole request. Anything you leave out falls back to the default shown in the catalog.

Input	Type	Required	What it does
`indicator`	string	yes	World Bank indicator code.
`countries`	array	yes	ISO2/ISO3 country codes.
`year_from`	integer	no	First year (default: all).
`year_to`	integer	no	Last year (default: latest).
`include_empty`	boolean	no	Keep rows whose value is null.
`max_results`	integer	no	How many datapoints to deliver at most (1–200). You pay only for delivered datapoints.

Pricing

World Bank API pricing

$0.0002 per delivered datapoint. A run that delivers nothing costs nothing: blocked pages, challenges and retries are on us, and the $2 monthly allowance covers about 10,000 datapoints before you spend anything.

What people build with the World Bank API

Three shapes of work this endpoint was designed around.

Macro feature panels

Pull GDP, inflation or population per country-year and join them onto your observations as model features keyed by country code and year.

Country enrichment joins

A market-sizing or lead table with a country column picks up population and income columns from one indicator call each.

Long-run trend series

year_from reaches back toward 1960, so a single request returns decades of one indicator for charting or back-testing.

World Bank API versus rolling your own

The differences that actually cost time when you build this in-house.

	DIY scraper	This collector
Panel shape	Paged JSON behind a metadata envelope	Long-format rows: country, year, value
Missing years	Nulls scattered through the series	Skipped by default, kept only on request
Batching countries	A request loop over country codes	Up to 30 countries in a single call

FAQ

Questions we get about the World Bank API.

Something else? Ask us →

Which indicator codes does the World Bank API accept?

Any code from the Bank's catalog of roughly 16,000 — NY.GDP.MKTP.CD for GDP in current US dollars, SP.POP.TOTL for population, FP.CPI.TOTL.ZG for CPI inflation — one indicator per call, across the countries you list.

Why are some years missing from the series?

Because the Bank publishes no figure for them. Null-value years are dropped so the panel stays dense; pass include_empty as true and they come back as rows with a null value instead.

Can I query world or regional aggregates?

Yes — aggregate codes such as WLD for the world total travel through the countries list exactly like ISO codes, so a global series and a country comparison come from the same call shape.

Is there a free World Bank API?

Every account gets $2 of credit every month with no card, which is about 10,000 delivered datapoints on this endpoint at $0.0002 each. It renews monthly, and a run that delivers nothing is never billed — so a failed or blocked attempt does not eat the allowance.

How much does one run cost?

Multiply the rows you actually receive by $0.0002. A run capped at 200 datapoints — the maximum for this collector — costs $0.04 if every row comes back, and less when the source has fewer. Volume tiers take up to 30% off, and GET /v1/scraper/collectors returns the price your key actually pays.
