                Дизайн REST API — основан на 4-летнем опыте работы
              
          
    Based on RESTful API Design — Step By Step Guide

Держать простым
Не забывать про методы
Использовать корректные статус-коды в ответах
Ресурсы как существительное, не глагол
Использовать множественное значение
Использовать пагинацию, а не выдавать всё разом
В коллекциях возвращать информацию о пагинации
Использовать квери-параметры для GET запросов, если нужно сузить выборку
