محدودیت‌ها

هر نشانی IP می‌تواند حدود 10 درخواست در ثانیه همراه با جهش‌های کوتاه بفرستد. بیش از آن، API با کد 429 و هدر Retry-After پاسخ می‌دهد. نتیجه‌هایی که هرگز تغییر نمی‌کنند یک روز کش می‌شوند، پس فراخوانی‌های تکراری فوری هستند.

پرسش و پاسخ

آیا به کلید API نیاز دارم؟

خیر. API رایگان و باز است. کافی است اندپوینت‌ها را از طریق HTTPS از سرور، یک اسکریپت یا مرورگر فراخوانی کنید.

چه فرمت‌های رنگی را می‌پذیرد؟

هر رنگ CSS: HEX، rgb()، hsl()، hwb()، lab()، lch()، oklab()، oklch() و color(display-p3 …)، به‌علاوه نام‌های CSS مثل navy، نام‌های رایج مثل royal blue و کلاس‌های Tailwind مثل sky-500.

خطاها چطور گزارش می‌شوند؟

خطاها با application/problem+json و همراه با یک title و یک detail برمی‌گردند که می‌گوید چه چیزی را باید اصلاح کنید، برای مثال وقتی یک رشته را نمی‌توان به‌عنوان رنگ خواند.
