Free Data

Curated by Vinod Kumar Jain & Amit Jain · All Frontier Global · free, no login

Everything on this network is built on data anyone can use for free. This is the honest list — what each source gives you, its official link, and a sample call you can paste into a browser — so you can pull the same numbers and check our work.

World Bank Open Data

Development and macro indicators for around 200 economies — GDP, trade, population, tariffs — through a free JSON API, licensed CC BY 4.0. This is where the country-comparison figures across the network come from.

https://api.worldbank.org/v2/country/IND/indicator/NY.GDP.MKTP.CD?format=json

Docs: World Bank API help desk

Crossref REST API

Metadata for scholarly works — titles, authors, journals, references — searchable by DOI or keyword with no key required. It is what powers the DOI Explorer.

Docs: api.crossref.org

open.er-api.com — exchange rates

Daily FX rates for 160+ currencies from ExchangeRate-API’s open, keyless endpoint, free with attribution. Useful for rough landed-cost and price conversions. For a contractual rate, use your bank’s quote, not this.

Docs: open-endpoint documentation

Open-Meteo

Forecasts, current conditions and long climate histories for any coordinates — free for non-commercial use, no key. Behind the climate notes on the city and relocation pages.

https://api.open-meteo.com/v1/forecast?latitude=28.61&longitude=77.21&current_weather=true

Docs: open-meteo.com/en/docs

Google News RSS

Free RSS feeds of headlines by keyword, topic or region — no key, standard RSS/XML. Keyword feeds keep the trade-news surfaces current. Usage is subject to Google’s terms.

Wikidata

The structured-data backbone under Wikipedia: facts about countries, cities, companies and people as machine-readable statements, released CC0 into the public domain, queryable by API and SPARQL.

https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q668&format=json

Docs: query.wikidata.org (SPARQL)

Wikipedia REST API

Article summaries, images and metadata for any topic through the REST endpoint, text CC BY-SA. Used for place and topic primers. Note the network’s own rule: Wikipedia is fine for orientation and is never a source for a figure.

Ground rules we follow, and recommend

Attribute the source. Each carries its own licence — CC BY, CC BY-SA, CC0, or the provider’s own terms. Link back, and respect the rate limits.
Cache politely, verify critically. Free tiers assume reasonable volumes. Where a decision involves money — an FX rate, a duty rate — confirm it against an authoritative quote before acting.
Official statistics beat aggregators. For anything going into a filing or a contract, go to the primary source — DGFT, CBIC, Eurostat, the national statistics office — even when an open API would be quicker.
An API is not a citation. These endpoints tell you what a source currently says. A figure still needs the source named and the date recorded, because both move.
