Choose Narwhal API when
You need Narwhal's published CPI, inflation, labour, GDP, and merchandise-trade operations with consistent periods, units, source metadata, REST, and hosted MCP.
Narwhal API vs World Bank API
The World Bank exposes a very large public development-data catalogue through its Indicators API. Narwhal publishes a much smaller set of normalized national economic operations, then connects those operations to the same REST and MCP account used for FX, Palmoil, and public holidays.
Decision
Choose the World Bank API for catalogue breadth, long annual histories, and direct access to World Bank datasets. Choose Narwhal when its published indicators and countries fit and you want source-specific national releases normalized into one application contract.
Choose the alternative when
You need the World Bank's nearly 16,000 time-series indicators, more than 45 databases, long development histories, or unauthenticated public access.
Evidence by requirement
The World Bank is an official source and a much broader catalogue. Narwhal is not presented as a breadth-equivalent replacement; compare the exact series definition, frequency, vintage, and country required.
| Requirement | Narwhal API | World Bank API |
|---|---|---|
| Product shape | Curated operations with a shared response model across published countries. | A source-native catalogue spanning development, debt, poverty, population, national accounts, and many other datasets. |
| Economic coverage | Published CPI, inflation, labour, GDP, and merchandise-trade jobs for the published countries. | Nearly 16,000 indicators across more than 45 databases, with many series extending beyond 50 years. |
| Formats | JSON REST resources and structured MCP tool responses. | XML, JSON, JSONP, JSON-stat, plus CSV, XML, and Excel downloads for supported queries. |
| Normalization | Narwhal owns stable fields for country, period, unit, source, release timing, freshness, and limitations. | Consumers work with World Bank indicator codes, source IDs, notes, organizations, frequencies, and dataset-specific semantics. |
| Access | One key and quota cover REST and hosted MCP across live Narwhal products. | The Indicators API does not require an API key; no first-party hosted MCP service was established in this review. |
