Narwhal API
Normalized CPI, inflation, labour, GDP, and merchandise-trade operations, with coverage varying by country and indicator.
Economic data APIs compared
A developer-focused comparison of normalized multi-country indicators, large time-series catalogues, official national statistics, forecasts, revision vintages, REST, and MCP access.
Decision
Choose Narwhal when its published indicators and country coverage fit the job and you value one normalized response model across economics and adjacent APIs. Choose a broader catalogue or official portal when you need a series, country, vintage, forecast, or table Narwhal does not publish.
Provider shortlist
Breadth is not treated as parity. Every provider organizes economics differently, so the correct choice begins with the exact indicator definition, country, period, revision policy, and interface required.
World Bank API
A large public development-indicator catalogue with long histories and no API key requirement.
IMF Data API
IMF macroeconomic and financial datasets, international comparability, and forecast products.
OECD Data Explorer
OECD statistics, structural metadata, and member or partner-economy comparison through SDMX.
Eurostat API
Detailed official EU statistics, harmonized classifications, regional dimensions, and source-native metadata.
ECB Data Portal
Official euro-area statistics, ECB reference exchange rates, metadata, and revision-aware retrieval.
Economist Intelligence Unit
Forward-looking country intelligence, proprietary macro forecasts, risk ratings, and expert analysis.
FRED
Broad economic-series discovery, source-native identifiers, transformations, releases, and revision vintages.
BLS Public Data API
The API suits analysis across the full range of published BLS survey data, with Version 2.0 adding net and percent changes.
Trading Economics
Near-global macroeconomic breadth, release calendars, forecasts, markets, and spreadsheet workflows.
API Ninjas
A focused inflation endpoint within a much wider general-purpose API catalogue.
e-Stat
The breadth and detail of official Japanese government statistics.
Alpha Vantage
Key US economic series inside a broader market-data and analytics API.
Compare the options
Best fit is not feature parity. Check the evidence and limitation together.
| Provider | Best for | Evidence checked | Important limitation |
|---|---|---|---|
| Narwhal API | Normalized CPI, inflation, labour, GDP, and merchandise-trade operations, with coverage varying by country and indicator. | The live contract documents source, unit, period, freshness, limitations, REST, and hosted MCP semantics. | Country and indicator coverage is curated. Economic-release calendars are available; a general macroeconomic forecast product is not. |
| World Bank API | A large public development-indicator catalogue with long histories and no API key requirement. | The Indicators API documents nearly 16,000 time series across more than 45 databases and several response and download formats. | Consumers work with World Bank indicator and source structures rather than Narwhal's normalized application operations. |
| IMF Data API | IMF macroeconomic and financial datasets, international comparability, and forecast products. | IMF Data publishes SDMX 2.1 and 3.0 APIs plus a separate DataMapper API for selected time series. | Dataset, frequency, methodology, vintage, and forecast status must be understood before comparing a value with a national release. |
| OECD Data Explorer | OECD statistics, structural metadata, and member or partner-economy comparison through SDMX. | The free API exposes OECD dataflows and structures in XML, JSON, and CSV formats. | Rate limits, large-query restrictions, dataflow versions, and multidimensional structures add integration work. |
| Eurostat API | Detailed official EU statistics, harmonized classifications, regional dimensions, and source-native metadata. | Eurostat documents Statistics, SDMX 2.1, SDMX 3.0, catalogue, JSON-stat, CSV, and bulk-access services. | Its multidimensional EU datasets are broader and structurally different from Narwhal's normalized operation model. |
| ECB Data Portal | Official euro-area statistics, ECB reference exchange rates, metadata, and revision-aware retrieval. | Its SDMX REST service supports data and structure discovery, changed-observation queries, previous versions, and multiple formats. | ECB reference rates and source-native dataflows are not equivalent to every national release or indicative FX feed. |
| Economist Intelligence Unit | Forward-looking country intelligence, proprietary macro forecasts, risk ratings, and expert analysis. | The EIU REST API documents data, articles, reports, views, forecasts, and risk intelligence across broad geography coverage. | It is a subscription intelligence platform, not a like-for-like observed-data API or self-service catalogue. |
| FRED | Broad economic-series discovery, source-native identifiers, transformations, releases, and revision vintages. | Its API is organized around series, sources, releases, categories, tags, observations, and real-time periods. | Consumers must understand series-specific definitions and structures rather than rely on one normalized cross-country operation model. |
| BLS Public Data API | The API suits analysis across the full range of published BLS survey data, with Version 2.0 adding net and percent changes. | Version 2.0 needs free registration renewed yearly and allows 500 daily queries, with up to 50 series and 20 years per query. | Requests require BLS series IDs, and BLS does not publish a catalogue of these identifiers. |
| Trading Economics | Near-global macroeconomic breadth, release calendars, forecasts, markets, and spreadsheet workflows. | Its checked documentation advertises 300,000 indicators and 196-country MCP coverage. | Its materially broader product and plan structure should be evaluated against the exact data and delivery needed. |
| API Ninjas | A focused inflation endpoint within a much wider general-purpose API catalogue. | Its Inflation API documents current and historical CPI or HICP rates for 38 countries. | The checked inflation endpoints are premium, and its non-economic catalogue should not be mistaken for economic depth. |
| e-Stat | The breadth and detail of official Japanese government statistics. | The official portal exposes statistical tables and metadata through XML, JSON, and CSV APIs. | It uses Japan-specific table and classification structures rather than Narwhal's normalized multi-country model. |
| Alpha Vantage | Key US economic series inside a broader market-data and analytics API. | The checked catalogue includes GDP, CPI, inflation, unemployment, retail sales, rates, and payroll series. | Its reviewed economic section is US-focused; the wider platform serves a different market-data use case. |
Choose by requirement
Normalized application contract
Choose Narwhal when the required countries and indicators are published and a stable shared response model is more useful than catalogue breadth.
Official international sources
Choose World Bank, IMF, OECD, Eurostat, or ECB when the application needs that institution's full catalogue, classifications, metadata, or revision model.
Research breadth and revisions
Choose FRED when series discovery, transformations, releases, and real-time vintage concepts are central to the work.
Global macro and forecasts
Choose Trading Economics for broad calendars, forecasts, and markets; choose EIU when proprietary country analysis, risk, and forward-looking intelligence are central.
Official national detail
Choose the source portal, such as e-Stat for Japan, when the application needs tables or classifications beyond Narwhal's normalized subset.
