Flag Feed is a REST API for developers that provides country flag images, primarily returning circular PNG flags via https://flagfeed.com/country/{code}. It uses ISO 3166-1 alpha-2 two-letter country codes and requires them to be lowercase, such as us, gb, and jp. The service does not require an API key or authentication, making it suitable for embedding flags directly as static image assets in websites, admin panels, or app interfaces.
Its core functionality is very focused: it returns image/png by country code, with CDN caching and Cache-Control: public, max-age=86400 for 24-hour caching. In addition to the image endpoint, it provides /api/info for version and endpoint information, and /status for health checks, making it suitable for uptime monitors or load balancer probes. The documentation states that CORS is open to all origins, so it can be used directly from the frontend. Examples cover curl, HTML, JavaScript, Python, and React, though the main documentation does not mention an official SDK.
The main content does not provide paid plans, free quotas, or commercial licensing information; it only states that no authentication is required. For rate limits, the documentation says reasonable IP-based throttling is applied, and requests exceeding the limit will return 429. For high-traffic scenarios, it recommends caching the images on your own CDN or storage. This means it is better suited as a lightweight resource service rather than core infrastructure that depends heavily on SLA commitments, quotas, or enterprise support.
The advantages are its extremely simple integrationβan HTML img tag is enough to use it. The response headers, error codes, and JSON error format are clear, and the caching strategy is explicit, which is friendly for frontend display use cases. The downsides are its narrow feature scope: the documentation only mentions circular PNG flags, with no evidence of SVG, WebP, size parameters, theme styles, or batch APIs. Country codes must be lowercase, so tolerance for input variation is limited. It also lacks information on open source availability, self-hosting, service support, and a full availability commitment.
Flag Feed is suitable for international websites, country selectors, user profiles, logistics and e-commerce platforms, travel products, and country indicators in data tables. If your team only needs a fast, authentication-free way to display flags, it is very easy to use. If you need long-term stability, controllable compliance, or localized deployment, you should evaluate alternatives such as building your own static asset library, Flagcdn, or REST Countries. The main content does not provide information on access from mainland China, so before production use, it is recommended to test HTTPS connectivity, CDN speed, and whether a proxy is needed. Payment information is also not disclosed.
