REST Countries

REST Countries is a free, open-source RESTful API that returns rich country reference data — ISO 3166-1 codes (cca2, cca3, ccn3, cioc), common/official and native names, translations, capitals, regions and subregions, continents, currencies, languages, calling codes, top-level domains, timezones, geographic coordinates, borders, area, population, demonyms, flags and coats of arms, postal code formats, Gini index, FIFA code, independence and UN membership status, driving side, and start of week. The canonical hosted instance runs at restcountries.com (v3.1) and the source is community-maintained at github.com/apilayer/restcountries (mirror of gitlab.com/restcountries/restcountries), licensed under MPL-2.0. The hosted API is unauthenticated and free; for production use the project encourages self-hosting from source.

REST Countries publishes 12 APIs on the APIs.io network, including All API, Alpha API, Capital API, and 9 more. Tagged areas include Countries, Geocoding, Geography, ISO 3166, and Open-Source.

The REST Countries catalog on APIs.io includes 2 JSON-LD contexts and 2 Spectral governance rulesets.

REST Countries’ developer surface includes documentation, authentication, pricing, and 16 more developer resources.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/rest-countries: open an issue to ask a question, or submit a pull request to add artifacts.
