Yes. REST API is one of the supported source types. Configure the endpoint and SleekRank caches the response per the configured duration. Public country APIs like restcountries.com return rich JSON with capitals, populations, languages, currencies, and flag URLs already structured. The cache duration controls how often the API is hit and how fresh the rendered pages are.

No. SleekRank renders pages from data you provide. The intro paragraphs need to live in your dataset (as a description column) or be written into the base template directly. For a serious reference site, the prose is the differentiator; using a column means each country gets its own intro, and using the base template gives a uniform structure across all 195.

Store the languages as an array in the data row, then use a list mapping to repeat a list-item template inside the base page. Multilingual countries — Switzerland, Belgium, India — show every official language consistently. The list-item template can include the language name, native name, and percentage of speakers if those fields are available in the source.

Reference the flag URL as a column in the data, then use a selector mapping to set the src attribute on an img element in the template. Public country APIs typically include flag URLs in SVG and PNG formats. The same approach works for coats of arms or other national symbols if those URLs are in the source.

Yes. Define a separate page group for cities with its own dataset and urlPattern. Cross-link from city pages to the parent country page in the template using the country slug. The same data philosophy — one source, multiple page groups — works for any related taxonomy: countries, regions, cities, languages, currencies.

Update the row in the source (or wait for the REST API's next refresh), flush the SleekRank cache, and the country page re-renders with the new figure on the next request. For sites pointing at a public API, the figure tracks the API automatically; for sites using a curated sheet, the editor controls when the change lands.

Add a recognition or status column and surface it explicitly on the page. Disputed territories — Taiwan, Western Sahara, Kosovo — benefit from an honest 'recognized by N states' field rather than a flattened claim. The data model can accommodate the dispute without forcing the site to take a side.

Yes. Add a continent or region column and either filter the same dataset for /asia/ and /europe/ pages, or build WordPress listing pages that group by region. Faceted browsing — by continent, by population range, by currency — lives in your theme; SleekRank handles the per-country detail pages.
