How this service works
Reference database of all 250 countries and territories: ISO 3166-1 codes, capitals, regions, population, area, currencies, languages, TLDs and calling codes. Look up a single country or list by region. Use this when an agent needs to 250 countries: codes, capitals, currencies, populations.
Output
Returns a JSON object or array containing country records. Each record includes the country name, ISO 3166-1 alpha-2 and alpha-3 codes, capital city, world region, population, land area, currency code and name, official languages, top-level domain (TLD), and international calling code. When filtering by country, a single record is returned; when listing, an array of matching countries is returned (optionally capped by a limit).
Example use cases
E-commerce checkout country picker
“I need the full list of all countries with their ISO codes, calling codes, and currencies so I can populate a checkout form — can you pull that from the countries database?”
Regional market research
“List all countries in Asia with their populations, currencies, and official languages so I can figure out which markets to target for our product launch.”
International dialing assistant
“What's the calling code, ISO code, and capital city for Nigeria? I need to set up an international phone directory entry.”

Endpoint
GEThttps://agentstoolshub.com/api/v1/databases/countries?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs authoritative, structured reference data about countries — such as ISO codes, capitals, currencies, languages, calling codes, or TLDs — for one country or a filtered regional list. It is ideal for populating forms, enriching user records with country metadata, building international phone or currency lookups, or answering factual geography questions. Prefer it over a general web search when structured, machine-readable output is needed reliably and consistently.
