자주 묻는 질문
API 키가 필요한가요?
아니요. API는 무료이며 공개되어 있습니다. 서버, 스크립트, 브라우저에서 HTTPS로 엔드포인트를 호출하기만 하면 됩니다.
어떤 색 형식을 받나요?
모든 CSS 색을 받습니다. HEX, rgb(), hsl(), hwb(), lab(), lch(), oklab(), oklch(), color(display-p3 …)에 더해 navy 같은 CSS 이름, royal blue 같은 일반 색 이름, sky-500 같은 Tailwind 클래스도 쓸 수 있습니다.
오류는 어떻게 알려 주나요?
오류는 application/problem+json 형식으로 title과 무엇을 고쳐야 하는지 알려 주는 detail을 담아 반환합니다. 예를 들어 문자열을 색으로 읽을 수 없을 때가 그렇습니다.
