You need a flag next to a country name. Two ways to get one, depending on whether you want text or an image.
Flag emoji (no requests)
Every country comes with a Unicode flag:
curl https://countries.dev/alpha/FR{ "name": "France", "alpha2Code": "FR", "flag": "🇫🇷",
"flags": { "svg": "https://upload.wikimedia.org/.../Flag_of_France.svg", "png": "https://.../France.png" } }The emoji is plain text — no image request, no sprite sheet, and it scales with the surrounding font:
<span>🇫🇷 France</span>One catch: Windows still renders flag emoji as the two-letter code, not a flag. If a chunk of your users are on Windows, use the image instead.
Flag image (SVG/PNG)
When you want a real rendered flag, or consistency across every platform, use the flags URLs from the response:
img.src = country.flags.svg; // or .png
img.alt = country.name;All of them at once
Building a list or a picker? Ask for just the flag fields:
curl "https://countries.dev/countries?fields=name,alpha2Code,flag,flags"Written by
