Cada punto final devuelve datos de conversión de tamaño para zapatos, anillos, sombreros y ropa, incluyendo medidas en varias unidades (mm, cm, in) y etiquetas de tamaño en diferentes sistemas (EE. UU., Reino Unido, UE, Japón)
Los campos clave incluyen "categoría" (tipo de artículo), "entrada" (tamaño del usuario y sistema), "tamaños" (tamaños convertidos en varios sistemas) y "rango" (variación de tamaño) Cada campo proporciona información esencial para las conversiones de tamaño
Los parámetros incluyen "tamaño" (el tamaño original), "sistema" (el sistema de tamaño utilizado) y para algunos puntos finales, "tipo" (por ejemplo, mujeres, hombres). Los usuarios pueden especificar estos para personalizar sus solicitudes de conversión
La respuesta está estructurada con una categoría principal, detalles de entrada y un objeto de tamaños que contiene tamaños convertidos para varios sistemas. Cada entrada de tamaño incluye el tamaño, valor, etiqueta y rango para mayor claridad
Los casos de uso típicos incluyen plataformas de comercio electrónico que necesitan conversiones de tallas para clientes internacionales minoristas de moda que proporcionan guías de tallas y aplicaciones que ayudan a los usuarios a encontrar sus tallas correctas entre marcas
Los usuarios pueden utilizar los datos devueltos haciendo referencia al objeto "sizes" para encontrar tamaños equivalentes en diferentes sistemas asegurando un ajuste preciso al comprar artículos de varias regiones o marcas
La precisión de los datos se mantiene a través de la adherencia a las normas de tamaño y actualizaciones regulares basadas en las prácticas de la industria La API también tiene en cuenta los rangos de variación de marcas para reflejar las discrepancias de tamaño en el mundo real
