Όρια
Κάθε διεύθυνση IP μπορεί να στέλνει περίπου 10 αιτήματα το δευτερόλεπτο, με σύντομες εξάρσεις. Πάνω από αυτό το όριο το API απαντά με 429 και κεφαλίδα Retry-After. Τα αποτελέσματα που δεν αλλάζουν ποτέ αποθηκεύονται στην cache για μία ημέρα, οπότε οι επαναλαμβανόμενες κλήσεις είναι άμεσες.
Ερωτήσεις και απαντήσεις
Χρειάζομαι κλειδί API;
Όχι. Το API είναι δωρεάν και ανοιχτό. Απλώς καλέστε τα endpoints μέσω HTTPS από τον διακομιστή σας, ένα script ή το πρόγραμμα περιήγησης.
Ποιες μορφές χρωμάτων δέχεται;
Οποιοδήποτε χρώμα CSS: HEX, rgb(), hsl(), hwb(), lab(), lch(), oklab(), oklch() και color(display-p3 …), καθώς και ονόματα CSS όπως navy, κοινά ονόματα όπως royal blue και κλάσεις Tailwind όπως sky-500.
Πώς αναφέρονται τα σφάλματα;
Τα σφάλματα επιστρέφονται ως application/problem+json με τίτλο και λεπτομέρεια που λέει τι πρέπει να διορθωθεί, για παράδειγμα όταν ένα string δεν μπορεί να διαβαστεί ως χρώμα.
