Limite

Fiecare adresă IP poate trimite cam 10 cereri pe secundă, cu scurte vârfuri. Peste această limită, API-ul răspunde cu 429 și antetul Retry-After. Rezultatele care nu se schimbă niciodată sunt păstrate în cache o zi, așa că apelurile repetate sunt instantanee.

Întrebări și răspunsuri

Am nevoie de o cheie API?

Nu. API-ul este gratuit și deschis. Apelează endpointurile prin HTTPS de pe serverul tău, dintr-un script sau din browser.

Ce formate de culoare acceptă?

Orice culoare CSS: HEX, rgb(), hsl(), hwb(), lab(), lch(), oklab(), oklch() și color(display-p3 …), plus nume CSS precum navy, nume uzuale precum royal blue și clase Tailwind precum sky-500.

Cum sunt raportate erorile?

Erorile folosesc application/problem+json, cu un titlu și un detaliu care spune ce trebuie corectat, de exemplu când un șir nu poate fi citit ca o culoare.
